net/hns3: fix RSS indirection table size

Browse Source 
The driver should not use the fixed value as the validity check of
RSS indirection table size with HW supported. As a result, it will
cause misjudgment when the RSS RETA size with HW supported have
changed.

Fixes: c37ca66f2b ("net/hns3: support RSS")
