net: ipa: replenish after delivering payload 



Replenishing is now solely driven by whether transactions are
available for a channel, and it doesn't really matter whether
we replenish before or after we deliver received packets to the
network stack.

Replenishing before delivering the payload adds a little latency.
Eliminate that by requesting a replenish after the payload is
delivered.
