[PATCH 8/9] ath10k: don't forget to replenish after fragmented Rx

[Michal Kazior]

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.
