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.
