wl1271: Fix warning about unsupported RX rate

While scanning, it is possible that beacon and probe response frames are received on other band than configured to the driver. In rx status handling this has caused "Unsupported RX rate from HW" warnings. This patch changes the wl1271_rate_to_index function to take the band of the received frame as a parameter instead of using value configuret to wl->band.
