Fix iwm(4) attach and firmware loading process such that a reboot after fw_update isn't required anymore. An iwm0 interface now appears if the firmware isn't installed at boot, but it has no MAC address. Firmware is now reloaded on ifconfig down/up and the MAC address is set if successful. test + ok phessler@
