libceph: fix potential hang in ceph_osdc_notify()
If the cluster becomes unavailable, ceph_osdc_notify() may hang even
with osd_request_timeout option set because linger_notify_finish_wait()
waits for MWatchNotify NOTIFY_COMPLETE message with no associated OSD
request in flight -- it's completely asynchronous.
Introduce an additional timeout, derived from the specified notify
timeout. While at it, switch both waits to killable which is more
correct.
