[SCSI] libfc: discovery restart sequence error fix
When an RSCN is received during fabric discovery, it restarts. After the restart, disc->seq_count was incremented, so when the first frame was received, it was considered "out of sequence". That left the state disc->active, preventing further discoveries. Change to advance the sequence count before parsing, so that it won't be changed after a potential restart.
