make sure 'length' is >=0 in afc_file_read
trying to read a negative amount of data doesn't make much sense, and the returned 'bytes' value will overflow if we try to do that. Just treat negative length values as an invalid argument. An alternative way of handling it would be to silently return OK/0 bytes read.
