ath10k: don't forget to replenish after fragmented Rx
In theory it was possible to drain entire HTT Rx
ring via fragmented Rx leading to Rx lockup.
In practice non-data traffic would always trigger
replenishment via the regular Rx handler.
For correctness sake make sure to replenish the
ring on fragmented Rx.
