Jeff Mahoney 85ab61fdfa btrfs: fix missing error return in btrfs_drop_snapshot 
commit e19182c0ff upstream.

If btrfs_del_root fails in btrfs_drop_snapshot, we'll pick up the
error but then return 0 anyway due to mixing err and ret.

Fixes: 79787eaab4 ("btrfs: replace many BUG_ONs with proper error handling")
