Move gethrtime() calls out of vdev queue lock
This dramatically reduces the lock contention on systems with slower
(non-TSC) timecounters.  With TSC the difference is minimal, but since
this lock is pretty congested, any improvement counts.  Plus I don't
see any reason to do it under the lock other than the latency of the
lock itself, which this change actually reduces.
