[SCSI] libfc: fix sequence-initiative WARN in fc_seq_start_next

When starting a new response sequence in a multi-sequence
exchange, a warning was issued that sequence initiative
wasn't held.

The bug was that sequence initiative was cleared by the previous
sequence due to the END_SEQ flag being on.  The intent may have
been to check LAST_SEQ.  Change just to check SEQ_INIT.
