Staging: rtl8192u: Add function to improve code quality

This patch introduces a new function for the authentication response
error check in the  ieee80211_rx_frame_softmac() function to fix the
indentation problem. It also adds the iotAction variable in the new
function to fix the "more than 80 characters per line" warning.
