While we are making changes in this code path, change the code for
ringing doorbell to set the WQE_COUNT to 0 for Receive Queue. The
hardware specification specifies that it should set to 0. Although
currently the hardware doesn't enforce the check, in the future releases
it may do.

And please split this cleanup into a separate patch, it doesn't sound
like it has to be done as part of the optimization.
