Subject: scsi: lpfc: Correct issues with FAWWN and FDISCs
Patch-mainline: v4.14-rc1
Git-commit: 176de5bb20271089d2ab120bb7737b66acc3c000
References: bsc#1050239,FATE#322918

When using fabric-assigned WWNs, the switch doesn't like copy of the
FLOGI payload, which includes valid VVL bits, to be used as the FDISC
payload.

Rather than wait for corrected switch firmware, ensure the VVL bits are
marked invalid on FDISCs.
