[GIT PULL] Btrfs fixes for 4.15-rc7

[David Sterba <dsterba@suse.com>]

Hi,

we have two more fixes for 4.15, aimed for stable. The leak fix is
obvious, the second patch fixes a bug revealed by the refcount API, when
it behaves differently than previous atomic_t and reports refs going
from 0 to 1 in one case.

No merge conflicts. Please pull, thanks.
