Patch from my store of obscure fixes

[Pete Zaitcev <zaitcev@redhat.com>]

Apparently, this patch comes from an expirience with a Clariion array
with some volumes disabled by operator. When Linux reboots, it
tries to spin them up and for some reason it times out, and
generally takes a very long time. I do suspect that START STOP UNIT
should return failure immediately, but perhaps it does not.
What do you guys think about this? Obviously a workaround, but
is it useful?
