[PATCH] ibmvfc: don't send implicit logouts prior to NPIV login

[Martin K. Petersen]

Tyrel,

> Commit ed830385a2b1 ("scsi: ibmvfc: Avoid loss of all paths during SVC
> node reboot") introduced a regression where when the client resets or
> re-enables its CRQ with the hypervisor there is a chance that if the
> server side doesn't issue its INIT handshake quick enough the client
> can issue an Implicit Logout prior to doing an NPIV Login. The server
> treats this scenario as a protocol violation and closes the CRQ on its
> end forcing the client through a reset that gets the client host state
> and next host action out of agreement leading to a BUG assert.

Applied to 5.7/scsi-fixes, thanks!
