This patch fixes the iwlwifi rfkill. It removes the input device from iwl3945,
adds support for RFKILL_STATE_HARD_BLOCKED and calls rfkill_force_state() to
update the state rather than accessing it directly.
The calls to iwl|iwl3945_rfkill_set_hw_state() had to be moved because
rfkill_force_state() cannot be called from an atomic context.
Tested on iwl3945 and seems to work fine.

This patch fixes monitor mode operation for iwlwifi.

Problems addressed:
1. when monitor mode was enabled, multiple, overlapped calls were being
made to 'iwl3945_bg_set_monitor'

2. when monitor mode was disabled (via the configure_filter callback),
the driver was still enabling monitor mode

3. when monitor mode was enabled, the selected channel was not set
(eg. 'iwconfig wlanx mode monitor channel n' DID NOT SET channel 'n'
when packet capture was subsequently enabled)

The iwlwifi drivers go to great lengths to avoid passing packets to
mac80211 they think shouldn't go there, while mac80211 can (of course!)
handle them very well.

Especially in the case of duplicate packets this is interesting
because it's such a performance hog (especially for IBSS networks)
while mac80211 does that work on the side without much effort.

This patch removes all that and leaves only what is absolutely
necessary for the hardware.
