    hw/audio/fmopl.c: Convert malloc, free to g_malloc0, g_new and g_free

    In accordance with QEMU's coding style guidelines, replace raw memory
    allocation functions (malloc/free) with their GLib equivalents
    (g_new/g_malloc0/g_free/g_clear_pointer).

    Also removes the old generic error-handling code from
    OPLOpenTable(), since the Glib functions abort the program automatically
    if memory is exhausted.
