When the RSS queues' types are not uniformed, i.e, mixed with normal Rx
queue and hairpin queue, PMD accept this flow after commit[1] instead of
rejecting it.
This because commit[1] creates Rx queue object as DevX type via DevX API
instead of IBV type via Verbs, in which the latter will check the queues'
type when creating Verbs ind table but the former doesn't check when
creating DevX ind table.
However, in any case, logically PMD should check whether the input
configuration of RSS action is reasonable or not, which should
include queues' type check as well as the others.
So add the check of RSS queues' type in validation function to fix issue.
