[PATCH 11/11] net/bnxt: Avoid submitting hwrm rss request when rss mode disabled

[Randy Schacher <stuart.schacher@broadcom.com>]

From: Shuanglin Wang <shuanglin.wang@broadcom.com>

On WH+, if rss mode isn't enabled, then there is no rss context.
Submitting HWRM_VNIC_RSS_CFG request to firmware would hit a failure.

The fix is to check the rss context. If no rss context, then don't
submit the hwrm request.
