currently the logic to calculate the rx rate is accessible
only in the cfg.c.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.
