description:
move softint_cleanup, which is a part of softint_fast_dispatch(),
into the section of code known as softint_fast_dispatch().

previous:

db> x/i softint_cleanup
netbsd:cpu_switchto+0xd4:       ld      t0,0(t8)

except that cpu_switchto() ends at cpu_switchto+0xd0.

now:

db> x/i softint_cleanup
netbsd:softint_fast_dispatch+0xa4:      ld      t0,0(t8)


tested on OCTEON.
