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.
