Gabriel Niebler 8ee922689d btrfs: turn fs_info member buffer_radix into XArray 
… named 'extent_buffers'. Also adjust all usages of this object to use
the XArray API, which greatly simplifies the code as it takes care of
locking and is generally easier to use and understand, providing
notionally simpler array semantics.

Also perform some light refactoring.
