[SCSI] ibmvfc: Fix Virtual I/O failover hang
If a Virtual I/O server fails in a dual virtual I/O server multipath configuration, ensure we delete all remote ports so that path failover can occur. For a single path configuration, the remote ports will go into devloss state. Signed-off-by: Brian King <brking@linux.vnet.ibm.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
