[SCSI] qla1280 command timeout

Original patch from Ian Dall in bugzilla. Set command timeout as
specified by the SCSI layer rather than hardcode it to 30 seconds. I
have received a couple of reports of people hitting this one with
various tape configurations and the patch looks obviously correct.

From http://bugzilla.kernel.org/show_bug.cgi?id=6275

Ian Dall <ian@beware.dropbear.id.au>:

The command sent to the card was using a 30second timeout regardless of the
timeout requested in the scsi command passed down from higher levels.
