This driver does not handle allocation failure when receiving data very
well. This patchset implements better handling in the case of allocation
failure.
Also do some necessary clean-up to implement this.
v2:
- squash 3 commits that were doing a single thing
- add new commit which removes a redundant assignment
- take device_init_rx_desc() out of unnecessary else condition.
- remove return statement at the end of void function
- add a missing rd = rd->next statement in device_rx_srv(): because
we already drop the current buffer, we should move on to the next
buffer in the ring where new data will be written to.
