Ranbir Singh 28a267af40 MdeModulePkg/Bus/Pci/UhciDxe: Fix FORWARD_NULL Coverity issues
The function UsbHcGetPciAddressForHostMem has

  ASSERT ((Block != NULL)); and

and the function UsbHcFreeMem has

  ASSERT (Block != NULL);

statement after for loop, but these are applicable only in DEBUG mode.
In RELEASE mode, if for whatever reasons there is no match inside for
loop and the loop exits because of Block != NULL; condition, then there
is no "Block" NULL pointer check afterwards and the code proceeds to do
dereferencing "Block" which will lead to CRASH.

Hence, for safety add NULL pointer checks always.
