[PATCH] cciss: use msleep() instead of schedule_timeout()

From: Nishanth Aravamudan <nacc@us.ibm.com>

Use msleep() instead of schedule_timeout() to guarantee the
task delays as expected. This change was ACK'ed before, but there were
multiple versions floating around and this hunk got lost, it seems.
