mgr / volumes: improve error handling

This cleans up lots of return-fu statements and make the source
look much more pythonic. Functions should raise an instance of
VolumeException() class wherever necessary (error handling).

mgr/balancer: fix fudge

next_* simply record some intermediate results when balancer tries
to find something to optimize, whereas best_* are used for the
final outputs.

Fix by comparing origin_ow with best_ow when determining if we
should use a valid fudge value.

mds: check dir fragment to split dir if mkdir makes it oversized.
In handle_client_mkdir we hit_dir (via hit_inode) in mkdir finish callback, but by then we might have overshot the split size (multiple mkdir in flight), so check dir fragment for an early chance to split the dir if mkdir makes it oversized.
