Subject: [ 156/171] rbd: kill notify_timeout option

3.4-stable review patch.  If anyone has any objections, please let me know.

------------------


From: Alex Elder <elder@...tank.com>

The "notify_timeout" rbd device option is never used, so get rid of
it.

(cherry picked from commit 84d34dcc116e117a41c6fc8be13430529fc2d9e7)
