cpu/x86/smm/smihandler.c: Simplify smm revision handling

The ASEG smihandler bails out if an unsupported SMM save state
revision is detected. Now we have code to find the SMM save state
depending on the SMM save state revision so reuse this to do the same.

This also increases the loglevel when bailing out of SMM due to
unsupported SMM save state revision from BIOS_DEBUG to BIOS_WARNING,
given that the system likely still boots but won't have a functioning
smihandler.
