Mac80211: currently the logic to calculate the rx rate is accessible
only in the cfg.c as the rate_idx_to_bitrate() is static function.
The rx rate calculation might be needed by other files(modules) of
mac80211(possibly debugfs). So grouping the rx rate calculation logic to
a separate function which can be accessed from other files. This change
will make the rx rate calculation implementation similar to tx rate.
