[PATCH master 6/7] fs: don't free device in remove callback

[Ahmad Fatoum]

The probe doesn't allocate the device, so remove shouldn't free it
either. This fixes a use-after-free on barebox shutdown:
Iterating over the list of devices requires that remove callbacks
don't remove the devices. This happened to work so far, because
apparently not much new allocations are going on during barebox
shutdown, but let's do it right.
