Bruce Evans 17008f5343 Throw away the complications in npxsave() and their infrastructure.
npxsave() went to great lengths to excecute fnsave with interrupts
enabled in case executing it froze the CPU.  This case can't happen,
at least for Intel CPU/NPX's.  Spurious IRQ13's don't imply spurious
freezes.  Anyway, the complications were usually no-ops because IRQ13
is not used on i486's and newer CPUs, and because SMPng broke them in
rev.1.84.  Forcible enabling of interrupts was changed to
write_eflags(old_eflags), but since SMPng usually calls npxsave() from
cpu_switch() with interrupts disabled, write_eflags() usually just
kept interrupts disabled.
