UefiCpuPkg/PiSmmCpuDxeSmm: Clean mCpuSmmRestrictedMemoryAccess

Browse Source 
Currently, mCpuSmmRestrictedMemoryAccess is only used by the
IsRestrictedMemoryAccess(). And IsRestrictedMemoryAccess() can
consume the PcdCpuSmmRestrictedMemoryAccess directly. Therefore,
mCpuSmmRestrictedMemoryAccess can be cleaned to simply the code
logic.
