btrfs: free btrfs_path before copying fspath to userspace
commit 8cf96b409d9b3946ece58ced13f92d0f775b0442 upstream.
btrfs_ioctl_ino_to_path() frees the search path after the userspace copy
from the temp buffer @ipath->fspath. Which potentially can lead to a lock
splat warning.
Fix this by freeing the path before we copy it to userspace.
