Btrfs: optimize set extent bit
The Btrfs set_extent_bit call currently searches the rbtree
every time it needs to find more extent_state objects to fill
the requested operation.
This adds a simple test with rb_next to see if the next object
in the tree was adjacent to the one we just found. If so,
we skip the search and just use the next object.
