scsi: lpfc: Fix unintentional double clearing of vmid_flag

The vport->vmid_flag is unintentionally cleared twice after an issue_lip
via the lpfc_reinit_vmid routine().

The first call to lpfc_reinit_vmid() is in lpfc_cmpl_els_flogi().  Then
lpfc_cmpl_els_flogi_fabric() calls lpfc_register_new_vport(), which calls
lpfc_cmpl_reg_new_vport() when the mbox command completes and calls
lpfc_reinit_vmid() a second time.

Fix by moving the vmid_flag clear outside of the lpfc_reinit_vmid() routine
so that vmid_flag is only cleared once upon FLOGI completion.
