libceph: update outdated comment in ceph_sock_write_space() 



The function try_write() was renamed to ceph_con_v1_try_write()
in commit 566050e1 ("libceph: separate msgr1 protocol
implementation") and subsequently moved to net/ceph/messenger_v1.c
in commit 2f713615 ("libceph: move msgr1 protocol implementation
to its own file").  Update the comment in ceph_sock_write_space()
accordingly.

[ idryomov: account for msgr2 in the updated comment as well ]
