fs_devices::num_devices can be zero only in unmounted context, and we
don't have any fsid specific kobjects in the unmoutend context. So no
need to call btrfs_sysfs_remove_fsid() in btrfs_free_stale_devices().

Signed-off-by: Anand Jain <anand.jain@oracle.com>
We implemented this in preparation to provide the fsid/device attributes
for the devices in unmoutned context as was proposed here [1].
