Subject: [PATCH 4.4 266/342] libceph: dont spam dmesg with stray reply warnings

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ilya Dryomov <idryomov@...il.com>

commit cd8140c673d9ba9be3591220e1b2226d9e1e40d3 upstream.

Commit d15f9d694b77 ("libceph: check data_len in ->alloc_msg()")
mistakenly bumped the log level on the "tid %llu unknown, skipping"
message.  Turn it back into a dout() - stray replies are perfectly
normal when OSDs flap, crash, get killed for testing purposes, etc.
