Fix fallout from i386 Meltdown preparation which is using interrupt
gates now. Interrupts for dna, fpu, and f00f_redirect were not
properly enabled. Thus npxintr() tried to get the kernel lock with
interrupts disabled causing a deadlock in pmap_tlb_shootwait().
Enable interrupts for dna, fpu, and f00f_redirect. dna and fpu
leave the kernel directly, thus they have to disable interrupts
again; f00f_redirect goes through calltrap which will enable
interrupts.
