Unfortunately a successful validation will result in status becoming 4 and I check if the return value is non-zero (rather than negative) in q6v5_mpss_load(). However, the next step in the process is to do a timed wait for the status to turn 4 or negative, so we should treat that snippet (check for MBA_AUTH_COMPLETE) as part of the validation and move it in here from q6v5_mpss_load().
