[SCSI] fcoe: fix broken fcoe interface reset
Reset using "fcoeadm -r" also needs to restart FIP before doing libfc lport reset, this is needed for new switch firmware requiring FIP solicitation before doing FLOGI again during reset. So this patch does this by doing fcoe_ctlr_link_down and then fcoe_ctlr_link_up to reset the interface. The fcoe_ctlr_link_down call path also does lport reset and then fcoe_ctlr_link_up re-starts the fabric login after doing FIP solicitation first to get reset feature working again.
