ath10k: fix num_sends_allowed replenishing
Commit e9bb0aa39 ("ath10k: delete struct ce_sendlist") broke num_sends_allowed incrementing. num_sends_allowed exceeded initial values and could overflow. This code was supposed to replenish num_sends_allowed for partial sendlist items (i.e. before final sendlist item from a sendlist was completed and could be processed by completion handlers). Fortunately it seems it did not cause any major breakage, yet. Signed-off-by: Michal Kazior <michal.kazior@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
