Btrfs: don't look at the extent buffer level 3 times in a row
We have a bit of debugging in btrfs_search_slot to make sure the level of the
cow block is the same as the original block we were cow'ing. I don't think I've
ever seen this tripped, so kill it. This saves us 2 kmap's per level in our
search. Thanks,
