Subject: [PATCH 074/270] libceph: eliminate connection state "DEAD"

3.5.7u1 -stable review patch.  If anyone has any objections, please let me know.

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

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

commit e5e372da9a469dfe3ece40277090a7056c566838 upstream.

The ceph connection state "DEAD" is never set and is therefore not
needed.  Eliminate it.
