Preserve a user RSS table whenever all entries fit the requested queue
count. Regenerate driver defaults. On growth, a retained user table does
not steer RSS traffic to the added queues until the user updates it.
Report table loss only after successful queue-set publication. The
non-swap allocation path still replaces invalid tables silently because
its callers do not consistently hold the notification's netdev lock.
Require RTNL for RSS setters to serialize them with reset/resume rebuilds.
