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.
