ceph: add new RECOVER mount_state when recovering session
When recovering a session (a'la recover_session=clean), we want to do all of the operations that we do on a forced umount, but changing the mount state to SHUTDOWN is can cause queued MDS requests to fail when the session comes back. Most of those can idle until the session is recovered in this situation. Reserve SHUTDOWN state for forced umount, and make a new RECOVER state for the forced reconnect situation. Change several tests for equality with SHUTDOWN to test for that or RECOVER.
