btrfs: fix missing snapshot drew unlock when root is dead during swap activation
[ Upstream commit 9c803c474c6c002d8ade68ebe99026cc39c37f85 ]
When activating a swap file we acquire the root's snapshot drew lock and
then check if the root is dead, failing and returning with -EPERM if it's
dead but without unlocking the root's snapshot lock. Fix this by adding
the missing unlock.
