ath10k: convert wow pattern from 802.3 to 802.11

Browse Source 
When trying to set wow wakeup patterns it fails with this command:

iw phyxx wowlan enable patterns offset xx+ IP address xx.xx.xx.xx

The reason is that the wow pattern from upper layer is in 802.3 format
for this case, it need to convert it to 802.11 format. The input
offset parameter is used for 802.3, but the actual offset firmware
need depends on rx_decap_mode, so that it needs to be recalculated.
Pattern of 802.3 packet is not same with 802.11 packet. If the
rx_decap_mode is ATH10K_HW_TXRX_NATIVE_WIFI, then firmware will
receive data packet with 802.11 format from hardware.

Tested with QCA6174 hw3.0 with firmware
WLAN.RM.4.4.1-00099-QCARMSWPZ-1, but this will also affect QCA9377.
This has always failed, so it's not a regression with new firmware
releases.
