iwm(4): Remove _mvm from the namespace.

This was inherited from iwlwifi, which drives devices supported by both
iwn(4) and iwm(4) in FreeBSD. In iwm(4) _mvm is meaningless, so remove
it. OpenBSD made the same change a long time ago. No functional change
intended.

iwm: Update the station add command for the new RX API.

The firmware expects a new version of the add-station command in
9000-series chips.

iwm - Track firmware state better, and improve handling in iwm_newstate().

* This avoids firmware resets in all the cases in iwm_newstate(). Instead
iwm_bring_down_firmware() is called, which tears down all the STA
connection state, according to the sc->sc_firmware_state value.

* Improve the behaviour of the LED blinking a bit, so it only blinks when
there really is a wireless scan going on.

* Print the newstate arg in debug output of iwm_newstate(), to help in
debugging.

This is inspired by the firmware state maintaining change in OpenBSD's iwm,
by stsp@openbsd.org (OpenBSD Git 0ddb056fb7370664b1d4b84392697cb17d1a414a).

* Remove duplicate mbufq_drain() from iwm_mvm_rm_sta(), this should be
handled in the caller.

[iwm] Adjust if_iwm_sta.h prototypes, don't pass iwm_node to rm_sta().

* Since a RUN -> INIT/SCAN transition seems to immediately destroy the
ieee80211_node for the AP, we can't read the in_assoc value from there.
Instead just directly pass that information via a boolean_t argument.

* Adds iwm_mvm_rm_sta_id() function, which just unconditionally removes
the station from the firmware.

* The iwm_mvm_rm_sta() function shouldn't actually remove the station from
firmware when we are still associated (i.e. during a RUN -> INIT/SCAN
transition).

* So when disassociating we will first call iwm_mvm_rm_sta() to drain the
queues/fifos. Later during disassociation we will then use
iwm_mvm_rm_sta_id() to actually remove the station.

the declarations to if_iwm_util.h for now.
