[SCSI] ibmvfc: Fixup host state during reinit
If an ELS is received while the virtual fibre channel adapter is going through its discovery, a flag is set which causes discovery to get re-driven. However, the hosts's state does not get set back to IBMVFC_INITIALIZING and scsi_block_requests does not get called again, which can result in queuecommand ops getting sent during discovery. This should not occur and may cause problems. One example is that we may no longer be logged into the target we send the command to, resulting in a failure which should not have occurred.
