Martin Radev ca31888271 OvmfPkg/X86QemuLoadImageLib: Handle allocation failure for CommandLine 
The CommandLine and InitrdData may be set to NULL if the provided
size is too large. Because the zero page is mapped, this would not
cause an immediate crash but can lead to memory corruption instead.
This patch just adds validation and returns error if either allocation
has failed.
