avcodec/av1dec: Always set ret before goto end

Before 0f8763fbea4e8816cd54c2a481d4c048fec58394, av1_frame_ref()
and update_reference_list() could fail and therefore needed to
be checked, which incidentally set ret. This is no longer happening,
leading to a potential use of an uninitialized value which is
also the subject of Coverity ticket #1596605.

Fix this by always setting ret before goto end; do not return
some random ancient value.
