iwlwifi: remove input device and fix rfkill state
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.
