drm/amdgpu/sdma: Clear SDMA rings after reset before starting them

Browse source

The ring contains commands that were emitted before the reset.
These need to be cleared to make sure the HW doesn't execute
them, because they are garbage at this point.

Note that the ring reset helpers will re-emit the commands
that are necessary after the reset.
