x86, mm: fault.c, refactor/simplify the is_prefetch() code

Impact: no functionality changed

Factor out the opcode checker into a helper inline.

The code got a tiny bit smaller:

   text    data     bss     dec     hex filename
   4632      32      24    4688    1250 fault.o.before
   4618      32      24    4674    1242 fault.o.after

And it got cleaner / easier to review as well.
