[SCSI] advansys: fix regression with request_firmware change
On newer kernels users of advansys module are reporting system hang when trying to load it without firmware files present. After looking closely at description on https://qa.mandriva.com/show_bug.cgi?id=53220, I think this is related to commit "[SCSI] advansys: use request_firmware". The problem is that after switch to request_firmware, asc_dvc->err_code isn't being set when firmware files aren't found or loading fails. err_code is used by the driver to judge if there was a fatal error or not, as can be seen for example on advansys_board_found, which will only return -ENODEV when err_code is set. Because err_code isn't being set when request_firmware fails, this is a change of behaviour of the code before request_firmware addition, making it continue to load and it fails later as the firmware wasn't really loaded.
