xfs: make sure aglen never goes negative in xfs_refcount_adjust_extents
Prior to calling xfs_refcount_adjust_extents, we trimmed agbno/aglen
such that the end of the range would not be in the middle of a refcount
record. If this is no longer the case, something is seriously wrong
with the btree. Bail out with a corruption error.
