Make it so that CEPH_MSG_DATA_PAGES data item can own pages,
fixing a bunch of memory leaks for a page vector allocated in
alloc_msg_with_page_vector(). Currently, only watch-notify
messages trigger this allocation, and normally the page vector
is freed either in handle_watch_notify() or by the caller of
ceph_osdc_notify(). But if the message is freed before that
(e.g. if the session faults while reading in the message or
if the notify is stale), we leak the page vector.
This was supposed to be fixed by switching to a message-owned
pagelist, but that never happened.
Fixes:
