net/ceph: Only clear SOCK_NOSPACE when there is sufficient space in the socket buffer
The Ceph messenger would sometimes queue multiple work items to write data to a socket when the socket buffer was full. Fix this problem by making ceph_write_space() use SOCK_NOSPACE in the same way that net/core/stream.c:sk_stream_write_space() does, i.e., clearing it only when sufficient space is available in the socket buffer.
