xfs: fix xfs_fsblock_t tracing
Using a static buffer in xfs_fmtfsblock means we can corrupt traces if
multiple CPUs hit this code path at the same. Just remove xfs_fmtfsblock
for now and print the block number purely numerical. If we want the
NULLFSBLOCK and NULLSTARTBLOCK formatting back the best way would be
a decoding plugin in the trace-cmd userspace command.
