MINOR: stick-table: move the task_queue() call outside of the lock

The write lock in stktable_requeue_exp() is quite expensive and should
be shortened as much as possible. There's no need for it when calling
task_queue() so let's move it out.

On a 80-thread machine with a peers section, the request rate increased
from 368k to 397k rps.
