2.6.34-stable review patch. If anyone has any objections, please let us know.

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

From: Brian King <brking(a)linux.vnet.ibm.com>

commit daa142d1773dd3a986f02a8a4da929608d24daaa upstream.

If a command times out resulting in EH getting invoked, we wait for the
aborted commands to come back after sending the abort. Shorten
the amount of time we wait for these responses, to ensure we don't
get stuck in EH for several minutes.
