[PATCH] UefiCpuPkg/CpuDxe: Do not ASSERT on AllocateMemorySpace() error

[PATCH] UefiCpuPkg/CpuDxe: Do not ASSERT on AllocateMemorySpace() error

[Jeff Fan]

Platform PEI may add LOCAL APIC memory mapped space into
EFI_HOB_MEMORY_ALLOCATION. Or platform may allocate this range before.

So, we skip AllocateMemorySpace()'s return status checking. Instead, we add one
DEBUG message for possible trace.

Did you actually hit the ASSERT on some platform soon after we discussed
it? :) Either way,

[Fan, Jeff]

Yes. Some platform sets memory allocation HOB. It makes sense. So, I remove ASSERT() from the code.
