autodisc: cast when assigning to different enum type

Gets rid of these warnings with clang:

    /home/smarchi/src/babeltrace/src/autodisc/autodisc.c:766:13: warning: implicit conversion from enumeration type 'auto_source_discovery_internal_status' (aka 'enum auto_source_discovery_internal_status') to different enumeration type 'auto_source_discovery_status' (aka 'enum auto_source_discovery_status') [-Wenum-conversion]
                            status = internal_status;
                                   ~ ^~~~~~~~~~~~~~~
