This patch fixes an issue with VlvTbltDevicePkg introduced
by commit:
https://github.com/tianocore/edk2/commit/5b91bf82c67b586b9588cbe4bbffa1588f6b5926
This patch filters the call to gCpu->SetMemoryAttributes()
if the requested attributes is 0. It also removes the #define
INVALID_CPU_ARCH_ATTRIBUTES that is no longer used.
