net: dsa: complete and fix the dsa unbinding

In order to cleanly unbind the dsa core, either as a module removal, or a platform device unbind, switch the allocation the their devm_ counterparts and complete the destroy functions.

First, the missing kfree were added, the remove function were completed then kfree were removed in favor to devm_ calls.

The last patch is an way to cleanly exit the probe when no switch is found in the discover process.

The patches are based on the current net.

v3:
- make checkpatch happy with 1/5 & 5/5
- fix 5/5 exit path with a goto
