btrfs: free btrfs_path before copying subvol info to userspace
commit 013c1c5585ebcfb19c88efe79063d0463b1b6159 upstream.
btrfs_ioctl_get_subvol_info() frees the search path after the userspace
copy from the temp buffer @subvol_info. This can lead to a lock splat
warning.
Fix this by freeing the path before we copy it to userspace.
