Darrick J. Wong e31c53a806 xfs: remove file_path tracepoint data 
The xfile/xmbuf shmem file descriptions are no longer as detailed as
they were when online fsck was first merged, because moving to static
strings in commit 60382993a2 ("xfs: get rid of the
xchk_xfile_*_descr calls") removed a memory allocation and hence a
source of failure.

However this makes encoding the description in the tracepoints sort of a
waste of memory.  David Laight also points out that file_path doesn't
zero the whole buffer which causes exposure of stale trace bytes, and
Steven Rostedt wonders why we're not using a dynamic array for the file
path.

I don't think this is worth fixing, so let's just rip it out.
