reduce byte swapping and spinlock usage in log write path


Date:  Mon Mar  3 09:54:29 PST 2003
Workarea:  jen.americas.sgi.com:/src/lord/xfs-linux.2.4

The following file(s) were checked into:
  bonnie.engr.sgi.com:/isms/slinx/2.4.x-xfs


Modid:  2.4.x-xfs:slinx:140714a
linux/fs/xfs/xfs_log.c - 1.265
        - only update h_numlog_ops and the iclog byte offset once per use of an
          iclog in a transaction, instead of once per log item. Keep 
h_numlog_ops
          in host byte order until we are about to write it out, then endian
          flip it.

linux/fs/xfs/xfs_log_priv.h - 1.86
        - minor cleanup, remove function argument which was always zero

linux/fs/xfs/xfs_log_recover.c - 1.257
        - drop second argument from xlog_assign_tail_lsn
