UefiCpuPkg/PiSmmCpuDxeSmm: Always initialze PSD 

The following commit moved the initialization of the
default PROCESSOR_SMM_DESCRIPTOR from MpService.c to
SmramSaveState.c and made this initialization
conditional on the value returned by the
SmmCpuFeaturesGetSmiHandlerSize() library function.

f12367a0b1

This changed the behavior of the PiSmmCpuDxeSmm module.
The initialization of the PROCESSOR_SMM_DESCRIPTOR is
moved before the call to SmmCpuFeaturesGetSmiHandlerSize()
to preserve the previous behavior.
