  Log:
  HAMMER 35B/many: Stabilization pass, cleanups.
  
  * Fix a B-Tree node load race which could result in an assertion.  A
    B-Tree node load is backed by a hammer_buffer and can race a buffer
    teardown.  Interlock the two and properly deal with a loading
    B-Tree node whos buffer gets ripped out from under it.
  
  * Fix an ordering issue with the volume->io.loading field, plus some
    cleanups.
