-If no firmware was present at all (or, presumably, all of the
-firmware files failed to parse), we end up unbinding by calling
-device_release_driver(), which calls remove(), which then in
-iwlwifi calls iwl_drv_stop(), freeing the 'drv' struct. However
-the new code I added will still erroneously access it after it
-was freed.
-
-Set 'failure=false' in this case to avoid the access, all data
-was already freed anyway.
