Patch 3 of 4
cciss: check for msi in interrupt_no_for_us
This patch checks to see if h->msi[x]_vector is set. We need this for a
following patch. Without this check we process one interrupt then stop
because in msi[x] mode the interrupt pending bit is not set. Not sure why we
didn't encounter this before.
