ath10k: add workqueue for RX path of sdio
For RX, it has two parts, one is to read data from sdio, another
is to indicate the packets to upper stack. Recently it has only
one thread to do all RX things, it results that it is sequential
for RX and low throughout, change RX to parallel for the two parts
will increase throughout.
This patch move the indication to a workqueue, it results in
significant performance improvement on RX path.
Udp rx throughout is 200Mbps without this patch, and it arrives
400Mbps with this patch.
Tested with QCA6174 SDIO with firmware
WLAN.RMH.4.4.1-00017-QCARMSWPZ-1
