[PATCH 41/54] net/bnxt: fix rss configuration when set to none

[Manish Kurup]

From: Kishore Padmanabha <kishore.padmanabha at broadcom.com>

If the rss hash type is set to none and the ports are stopped and
started again, the check for rss hash type was not allowing the
bnxt driver to populate the correct rx rings in the vnic rss list.
This causes the subsequent calls to rss configuration fail since
the rss list is not configured and have stale data causing the
firmware to reject the rss configuration.

The rss hash type of none should not be ignored during configuration,
it is a valid configuration and should be applied. When rss hash
type is none, the rss context is disabled and there should be no
rss algorithm applied to the incoming traffic.
