    if_iwm - Move iwm_read_firmware() call into iwm_attach().
    
    * We should load the firmware exactly once before the driver really
      initializes the hardware the first time, and unload it at detach time.
      There is no need to retrieve the firmware during execution of
      iwm_mvm_load_ucode_wait_alive(), we should make sure we already have the
      firmware data at hand before that.
    
    * The existing sc_preinit_hook code fails to deal with the case where
      if_iwm is loaded by the loader (or is statically linked) and the
      firmware needs to be loaded from disk. So we can just call
      iwm_read_firmware() from iwm_attach() directly.
    
    * A separate solution will have to be added to properly defer the firmware
      loading during bootup, until the necessary filesystem is mounted.
