[SCSI] libfc: rearrange code in fc_disc_gpn_ft_resp()

Code cleanup for fc_disc_gpn_ft_resp().

Some of the fc_disc.c code was poorly formatted. For example, some lines
in fc_disc.c were unnecessarily truncated and the buf variable could
be eliminated.

Also moved the increment of seq_count into fc_disc_gpn_ft_parse(), to
avoid doing it separately before each call.
