[B43LEGACY]: Change the hardware radio enable logic and cleanup code

Browse Source 
This change cleans up the radio-related messages in several ways.

(1) The state of the rfkill switch is assumed to be on, rather than
    tested. Now, any user without such a switch will not see any
    messages. For devices with such a switch, a message will be
    logged only if the initial state is off, or if the switch is toggled.
(2) The routine for testing the switch state is no longer inline.
(3) The LED handling routine is simplified.
(4) The "Radio turned off" message that has confused some users has been
    changed to "Radio initialized".

This patch is patterned after a similar change to b43 by Michael Buesch.
