[ 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:
=9A393441 =9A =9A2904 =9A =9A2952 =9A399297 =9A 617c1 linux-2.6-xfs7-TEST/f=
s/xfs/xfs.o
=9A393289 =9A =9A2904 =9A =9A2952 =9A399145 =9A 61729 linux-2.6-xfs8-TEST/f=
s/xfs/xfs.o

Compile tested only.
