Johannes Thumshirn f6f0da564c btrfs: don't BUG_ON() in btrfs_drop_extents() 
btrfs_drop_extents() calls BUG_ON() in case the counter of to be deleted
extents is greater than 0. But all of these code paths can handle errors,
so there's no need to crash the kernel. Instead WARN() that the condition
has been met and gracefully bail out.
