    gdb: use get_current_frame consistently in print_stop_location
    
    In print_stop_location, in the PRINT_UNKNOWN case we currently use a
    strange mix of get_current_frame and get_selected_frame.  This works
    fine because at the point print_stop_location is called the selected
    frame will always be the current frame, but calling these two
    different functions is confusing, at least for me.
    
    Since bpstat_print selects the frame to print (which usually is the current
    frame, but not always), the correct frame to use is the selected frame after
    the bpstat_print call.
    
    Assign the selected frame to a variable print_frame, and use it throughout the
    function.
    
    There should be no user visible changes after this commit.
