iwlwifi: fix unhandled interrupt when HW rfkill is on
This patch fixes unhandled interrupt when HW rfkill is on during devices start up. The behavior changes, now open is successful even when rfkill is on. This is to align with the situation when rfkill is set on after opening. Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
