    gmain: Initialise a variable
    
    This fixes a scan-build warning:
    ```
    ../../../../source/glib/glib/gmain.c:4193:18: warning: 2nd function call argument is an uninitialized 
value [core.CallAndMessage]
      while ((nfds = g_main_context_query (context, max_priority, &timeout, fds,
                     ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    ```
    
    This is a valid situation which can occur if the preceding
    `g_main_context_prepare()` call returns `FALSE` and doesn’t set
    `max_priority`.
