Btrfs: fix subvol_name leak on error in btrfs_mount()
btrfs_parse_early_options() can fail due to error while scanning devices (-o device= option), but still strdup() subvol_name string: mount -o subvol=SUBV,device=BAD_DEVICE <dev> <mnt> So free subvol_name string on error. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
