Fixes for XLR network accelerator driver (nlge).

- Process some tx done messages in the transmit path, to ensure that
  the XLR NA tx done FIFO does not overflow.
- Add a message ring handler API to process atmost a given number of
  messages from a specified bucket mask. This will be used to process
  the tx done messages
- Add a callout to restart transmit in the case transmit gets blocked.
- Update enable_msgring_int() and disable_msgring_int(), remove unused
  args and make static.
