LOG: [flang][driver] Fix a small bug (auto vs auto&)

This bug hasn't affected us yet as our usage is too basic, i.e. we don't
rely on the defaults provided by `SetDefaultFortranOpts` just yet. This
will change shortly.

Added: 
    

Modified: 
    flang/lib/Frontend/CompilerInvocation.cpp

Removed:
