This is a bit awkward from drivers' point of view, we have to add the
same code to all mac80211 drivers using either SPI or SDIO buses.
What about adding a new inline function ieee80211_rx_ni() which would
disable bottom halves like above and call ieee80211_rx()? IMHO that's
easier for the driver developers to understand and also easier to
document ("use this function when calling from process context"). If
this is acceptable, I can create a patch.
