wl1271: Fix RX data path frame lengths
The current frame length used by the driver for RX frames is the SPI bus transfer length. This length has padding bytes, which do not belong to the WLAN frame. As there is no other length information in the WLAN frame except the skb length this problem caused for instance extra ESSID's to be listed at the end of scan results (IE id 0) with zero length. Fix the frame length by removing padding.
