xfs: use DECLARE_EVENT_CLASS

Using DECLARE_EVENT_CLASS allows us to to use trace event code
instead of duplicating it in the binary.  This was not available
before 2.6.33 so it had to be done as a separate step once the
prerequisite was merged.

This only requires changes to xfs_trace.h and the results are
rather impressive:
