    RPC: fix crash when using "Dissect unknown RPC program numbers" option
    
    When using this option, rpc_prog_info_value structure is not fully initialized.
    Depending on the memory allocator used, this can lead to a NULL pointer
    dereference or an access to a random memory block.
    Ensure that the structure if fully initialized and test pointer before
    dereferencing it.
