btrfs: remove redundant BUG_ON() from __btrfs_inc_extent_ref()

Browse Source 
At __btrfs_inc_extent_ref() we are doing a BUG_ON() if we are dealing with
a tree block reference that has a reference count that is different from 1,
but we have already dealt with this case at run_delayed_tree_ref(), making
it useless. So remove the BUG_ON().
