IntelFsp2Pkg: Fix NASM X64 build warnings. 

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4377

Fix below warnings generated by NASM X64 build:
/X64/FspHelper.iii:26: warning: signed dword value exceeds bounds
/X64/FspHelper.iii:35: warning: signed dword value exceeds bounds
/X64/FspApiEntryT.iii:320: warning: dword data exceeds bounds

Also replaced "cmp reg, 0" with "test reg, reg" per optimization
suggestion.
