GregorKopka f9f3f1ef98 Removing unneeded mutex for reading vq_pending_tree size 
Locking mutex &vq->vq_lock in vdev_mirror_pending is unneeded:

* no data is modified
* only vq_pending_tree is read
* in case garbage is returned (eg. vq_pending_tree being updated
  while the read is made) the worst case would be that a single
  read could be queued on a mirror side which more busy than thought

The benefit of this change is streamlining of the code path since
it is taken for *every* mirror member on *every* read.
