[ resend: now with patch attached! :) ]

Hi David,

Seven xfs_trans_XXX functions declared in xfs_trans.h
are not using "tp" parameter in non-debug builds,
but it still takes stack space since these functions
are not static and gcc cannot optimize it out.

This patch removes these parameters using #define hack
which makes them "disappear" without the need of uglifying
every callsite with #ifdefs.

Code size difference on 32-bit x86:
š393441 š š2904 š š2952 š399297 š 617c1 linux-2.6-xfs7-TEST/fs/xfs/xfs.o
š393289 š š2904 š š2952 š399145 š 61729 linux-2.6-xfs8-TEST/fs/xfs/xfs.o

Compile tested only.
