Fix the following asmvalidate warnings:
asmvalidate: arch/x86/crypto/ghash-clmulni-intel_asm.o: clmul_ghash_mul():
missing FP_SAVE/RESTORE macros
asmvalidate: arch/x86/crypto/ghash-clmulni-intel_asm.o:
clmul_ghash_update(): missing FP_SAVE/RESTORE macros
These are non-leaf callable functions, so save/restore the frame pointer
with FP_SAVE/RESTORE.
