ath9k currently forces hw->max_rate_tries to 4 to work around rate
control inefficiencies. This has some negative side effects, such as
rate_control_send_low also using a maximum of 4 tries, which could
negatively affect reliability of unicast management frames.
This patch pushes the retry limit to the rate control instead, and
allows it to use more tries on the last stage to prevent unnecessary
packet loss.

The device has to be marked as invalid before
registering the ISR. HW initialization takes place
after the ISR has been registered, and the invalid
flag is eventually cleared in the ->stop() callback.

The device initialization and termination functions
were messy and convoluted. Introduce helper functions
to clarify init_softc() and simplify things in general.
