libceph: un-backoff on tick when we have a authenticated session
commit facb9f6eba3df4e8027301cc0e514dc582a1b366 upstream. This means that if we do some backoff, then authenticate, and are healthy for an extended period of time, a subsequent failure won't leave us starting our hunting sequence with a large backoff. Mirrors ceph.git commit d466bc6e66abba9b464b0b69687cf45c9dccf383. Cc: stable@vger.kernel.org # 4.7+ Signed-off-by: Ilya Dryomov <idryomov@gmail.com> Reviewed-by: Jason Dillaman <dillaman@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
