[PATCH 5/8] btrfs: Don't BUG_ON errors in __finish_chunk_alloc()

[Mark Fasheh <mfasheh@suse.de>]

From: Mark Fasheh <mfasheh@suse.com>

All callers of __finish_chunk_alloc() BUG_ON() return value, so it's trivial
for us to always bubble up any errors caught in __finish_chunk_alloc() to be
caught there.
