    TRANSUM: fix crash when switching profiles
    
    "output_rrpd" is NULL when the TRANSUM dissector is disabled (which is
    the default behavior). When switching to a profile where the dissector
    is enabled, redissection happens, but without invoking the init routine.
    This leads to a crash when dissect_transum tries to query "output_rrpd".
    
    Fix this by creating the map unconditionally. Use wmem_map_new_autoreset
    since its contents should be erased for new capture files.
