net: Don't return invalid table id error when dumping all families
When doing a route dump across all address families, do not error out if the table does not exist. This allows a route dump for AF_UNSPEC with a table id that may only exist for some of the families. Do return the table does not exist error if dumping routes for a specific family and the table does not exist. Signed-off-by: David Ahern <dsahern@gmail.com> Signed-off-by: David S.
