exec: Notify cpu_register_map_client caller if the bounce buffer is available
The caller's workflow is like
if (!address_space_map()) {
...
cpu_register_map_client();
}
If bounce buffer became available after address_space_map() but before
cpu_register_map_client(), the caller could miss it and has to wait for the
next bounce buffer notify, which may never happen in the worse case.
Just notify the list in cpu_register_map_client().
