scsi: csiostor: fix NULL pointer dereference in csio_vport_set_state()



[ Upstream commit fe35a40e675473eb65f2f5462b82770f324b5689 ]

Assign fc_vport to ln->fc_vport before calling csio_fcoe_alloc_vnp() to
avoid a NULL pointer dereference in csio_vport_set_state().

ln->fc_vport is dereferenced in csio_vport_set_state().
