[PATCH iproute2 v2] devlink: Fix setting parent for 'rate add'

Setting a parent during creation of the node doesn't work, despite
documentation [1] clearly saying that it should.

[1] man/man8/devlink-rate.8

Example:
$ devlink port function rate add pci/0000:4b:00.0/node_custom parent node_0
  Unknown option "parent"

Fix this by passing DL_OPT_PORT_FN_RATE_PARENT as an argument to
dl_argv_parse() when it gets called from cmd_port_fn_rate_add().

Fixes: 6c70aca76ef2 ("devlink: Add port func rate support")
