Back in commit a55e073088 ("xfs: only allow reaping of per-AG
blocks in xrep_reap_extents"), we removed from the reaping code the
ability to handle bmbt blocks. At the time, the reaping code only
walked single blocks, didn't correctly detect crosslinked blocks, and
the special casing made the function hard to understand. It was easier
to remove unneeded functionality prior to fixing all the bugs.
Now that we've fixed the problems, we want again the ability to reap
file metadata blocks. Reintroduce the per-file reaping functionality
atop the current implementation. We require that sc->sa is
uninitialized, so that we can use it to hold all the per-AG context for
a given extent.
