[SCSI] libfc: cache align struct fc_fcp_pkt fields
Re-arrange its fields to avoid padding and have better cacheline alignments. Removed not used start_time, end_time and last_pkt_time fields. This all reduced this struct size to 448 from 480 and that also reduced one cacheline on x86_64 beside eliminating 8 pads. However kept logical fields together.
