Subject: [PATCH 3.10 016/103] ipmi: Reset the KCS timeout when starting error recovery

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

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

From: Corey Minyard <cminyard@...sta.com>

commit eb6d78ec213e6938559b801421d64714dafcf4b2 upstream.

The OBF timer in KCS was not reset in one situation when error recovery
was started, resulting in an immediate timeout.
