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.
