Commit 17793e3e6a49 ("Btrfs-progs: extend the extent cache for the
device extent") extended the cache extent APIs to support objectid to
distinguish between phyisical extents with same dimensions but on
different devices. However, it seems that this particular function is
not used to allocate a device extent with accompanying objectid.
Instead such extents as processed solely by insert_device_extent_record.
Remove the unused code as a result.
