Isolated mode prevents global RSS from being enabled and configured.
However, an application may need to query default RSS key and hash
functions when a flow rule with RSS action is added which does not
contain custom RSS key or hash function choice. In this case
global RSS key and hash functions will be used to handle the rule,
and there should be some way for the application to query these
global default settings to clarify expectations on the traffic
distribution.

Earlier a patch was made to support change of Rx queue
number. That patch added goto label in wrong place
because reconfiguration with the same number of queues
results in skipping not only queue init but also RSS
settings. If a user configures device with RSS multiqueue
mode and then wants to stop it and reconfigure without RSS,
this change will be ignored and RSS will continue working.
Move the label in the right place and rename it to describe it.
