Ranbir Singh dd49d448b0 MdeModulePkg/Bus/Pci/EhciDxe: Fix FORWARD_NULL Coverity issues
The function UsbHcGetPciAddressForHostMem has

    ASSERT ((Block != NULL));

and the 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 the
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.
