Get rid of the device reset hack in iwm_newstate_task().

Instead, maintain firmware state in accordance to the current net80211
state by adding/updating/removing MAC config, PHY->MAC binding, and the
station in the firmare station table (we only add the AP to this table).
By eliminating the iwm_stop() call from iwm_newstate_task(), this change
prepares future work on fixing races between ioctls and tasks scheduled
by this driver.

There's a known new occasional fatal firmware error which results in
the message "iwm0: could not remove MAC context (error 35)"
I expect to fix this soon.

tested by tb@ on 7265, by jcs@ on 8265, and by myself on 7260/7265/8260
