[SCSI] libfcoe: fip: fix non-FIP-mode FLOGI state after reset.

Browse Source 
When a reset is sent using fcoeadm on a non-FIP mode NIC,
there's no link flap, so the fcoe_ctlr stays in non-FIP mode.

In that case, FIP wasn't setting the flogi_oxid or map_dest flag,
causing the FLOGI to be sent with the both wrong source MAC and
the wrong destination MAC address, causing it to fail.

This leads to a non-functioning HBA until a link flap or
instance delete/create.
