x86/speculation: Change misspelled STIPB to STIBP
STIBP stands for Single Thread Indirect Branch Predictors. The acronym,
however, can be easily mis-spelled as STIPB. It is perhaps due to the
presence of another related term - IBPB (Indirect Branch Predictor
Barrier).
Fix the mis-spelling in the code.
