Fix issue reported by alc :
MIPS doesn't really need to use atomic_cmpset_int() in situations like
this because the software dirty bit emulation in trap.c acquires
the pmap lock. Atomics like this appear to be a carryover from i386
where the hardware-managed TLB might concurrently set the modified bit.
