Some functions across OVMF don't check pointer arguments for
validity, which causes null pointer dereferences and crashes
in the SCT test suite.

This series adds checks to return EFI_INVALID_PARAMETER if a
pointer argument is NULL.

v2:
- Add Liming Gao to Cc [Ard]
- Turn individual patches into a series [Ard]
- Fix issue with corrupted patches [Ard]
