Fix early exit in modref_merge_call_site_flags

Browse source 
When adding support for static chain and return slot flags I forgot to update
early exit condition in modref_merge_call_site_flags.  This yields to wrong
code as demonstrated by the Fortran testcase attached to PR (which I hope
someone will help me to turn into testuite one).
