[SCSI] ibmvscsi: Add suspend/resume support
Adds support for resuming from suspend for IBM VSCSI devices. We may have lost an interrupt over the suspend, so we just kick the interrupt handler to process anything that is outstanding. We expect to find a transport event indicating we need to reestablish our CRQ. Signed-off-by: Brian King <brking@linux.vnet.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
