Bob Feng 5a8bc527b3 OvmfPkg/LinuxInitrdDynamicShellCommand: Cast UNIT64 to UNITN in assignment
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2580

Ovmf build failed on Windows with VS2017 tool chain.
The error message like:

OvmfPkg\LinuxInitrdDynamicShellCommand\LinuxInitr
 dDynamicShellCommand.c(199): error C2220: warning treated as error -
 no 'object' file generated
OvmfPkg\LinuxInitrdDynamicShellCommand\LinuxInitrdDynamicShellCommand.c(199):
warning C4244: '=': conversion from 'UINT64' to 'UINTN',
possible loss of data

This patch is to cast UINT64 type to UINTN type
when doing the variable assignment.

Ard Biesheuvel 6c6fef0247 OvmfPkg/LinuxInitrdDynamicShellCommand: fix uninitialized status return
The Linaro CI reports:

  OvmfPkg/LinuxInitrdDynamicShellCommand/LinuxInitrdDynamicShellCommand.c:132:7:
  error: variable 'Status' is used uninitialized whenever 'if' condition is
                false [-Werror,-Wsometimes-uninitialized]
    if (mInitrdLoadFile2Handle != NULL) {
        ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  OvmfPkg/LinuxInitrdDynamicShellCommand/LinuxInitrdDynamicShellCommand.c:141:10:
  note: uninitialized use occurs here
    return Status;
           ^~~~~~
  OvmfPkg/LinuxInitrdDynamicShellCommand/LinuxInitrdDynamicShellCommand.c:132:3:
  note: remove the 'if' if its condition is always true
    if (mInitrdLoadFile2Handle != NULL) {
    ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  OvmfPkg/LinuxInitrdDynamicShellCommand/LinuxInitrdDynamicShellCommand.c:130:23:
  note: initialize the variable 'Status' to silence this warning
    EFI_STATUS    Status;
                      ^
                       = 0

Fix this by pulling the return of Status into the conditional block where
it is assigned, and return EFI_SUCCESS otherwise.

Ard Biesheuvel ecb30848fd OvmfPkg/LinuxInitrdDynamicShellCommand: bail if initrd already exists
Before taking any actions, check if an instance of the LoadFile2 exists
already on the Linux initrd media GUID device path, and whether it was
provided by this command. If so, abort, since no duplicate instances of
the device path should exist.

Ard Biesheuvel 2632178bc6 OvmfPkg: add 'initrd' shell command to expose Linux initrd via device path
Add a new 'initrd' command to the UEFI Shell that allows any file that is
accessible to the shell to be registered as the initrd that is returned
when Linux's EFI stub loader invokes the LoadFile2 protocol on its special
vendor media device path.
