ath11k: avoid additional access to ath11k_hal_srng_dst_num_free
In ath11k_dp_process_rx(), after processing rx_desc from
ath11k_hal_srng_dst_get_next_entry(), ath11k_hal_srng_dst_num_free()
is accessed everytime because of done flag is not set.
To avoid this additional access to ath11k_hal_srng_dst_num_free(),
increment total_msdu_reaped only when continuation is not set and
update done flag correspondingly.
