Subject: [PATCH] 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.
