Subject[ 066/171] ceph: messenger: reset connection kvec caller
Date
3.4-stable review patch.  If anyone has any objections, please let me know.

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

From: Alex Elder <elder@inktank.com>

(cherry picked from commit 84fb3adf6413862cff51d8af3fce5f0b655586a2)

Reset a connection's kvec fields in the caller rather than in
prepare_write_connect(). This ends up repeating a few lines of
code but it's improving the separation between distinct operations
on the connection, which we can take advantage of later.
