[PATCH AUTOSEL 6.7 072/108] scsi: lpfc: Reinitialize an NPIV's VMID data structures after FDISC

[ Upstream commit 8dc8eb89f4df74593ba4bf30c3d31a0fc6d3ea47 ]

After a follow up FDISC cmpl, an NPIV's VMID data structures are not
updated.

Fix by calling lpfc_reinit_vmid and copying the physical port's vmid_flag
to the NPIV's vmid_flag in the NPIV registration cmpl code path.
