Chris Mason 7c2fe32a23 Btrfs: Fix add_extent_mapping to check for duplicates across the whole range ...

add_extent_mapping was allowing the insertion of overlapping extents.
This never used to happen because it only inserted the extents from disk
and those were never overlapping.

But, with the data=ordered code, the disk and memory representations of the
file are not the same.  add_extent_mapping needs to ensure a new extent
does not overlap before it inserts.
