Fix locking problem in _hash_squeezebucket() / _hash_freeovflpage().
A bucket squeeze operation needs to lock each page of the bucket
before releasing the prior page, but the previous coding fumbled the
locking when freeing an overflow page during a bucket squeeze
operation. Commit 6d46f4783efe457f74816a75173eb23ed8930020
introduced this bug.
Amit Kapila, with help from Kuntal Ghosh and Dilip Kumar, after
an initial trouble report by Jeff Janes. Reviewed by me. I also
fixed a problem with a comment.
