x86/ucode/intel: Adjust microcode_sanity_check() to not take void *

microcode_sanity_check()'s callers actually call it with a mixture of
microcode_intel(/patch) and microcode_header_intel pointers, which is fragile.

Rework it to take struct microcode_patch *, which in turn requires
microcode_update_match()'s type to be altered.

No functional change - compiled binary is identical.
