When we're scanning an extent mapping inode fork, ensure that every rmap record for this ifork has a corresponding bmbt record too. This (mostly) provides the ability to cross-reference rmap records with bmap data. The rmap scrubber cannot do the xref on its own because that requires taking an ilock with the agf lock held, which violates our locking order rules (inode, then agf). Note that we only do this for forks that are in btree format due to the increased complexity; or forks that should have data but suspiciously have zero extents because the inode could have just had its iforks zapped by the inode repair code and now we need to reclaim the old extents.
