scsi: qedf: Add missing fc_disc_init call after allocating lport

When receiving an unsolicited frame we could crash on a list traversal in
fc_rport_lookup while searching the rport which is associated with our
lport.

Initialize the lport's discovery node after allocating the lport in
__qedf_probe().
