[PATCH 08/17] net/bnxt: fix to reconfigure the VNIC's default receive ring

[Kalesh A P <kalesh-anakkur.purayil@broadcom.com>]

From: Somnath Kotur <somnath.kotur@broadcom.com>

When an Rx queue is stopped and restarted, as part of that workflow,
for cards that have ring groups, we free and reallocate the ring group.
This new ring group is not communicated to the VNIC though via
HWRM_VNIC_CFG cmd.
Fix to issue HWRM_VNIC_CFG cmd on all adapters now in this scenario.

Fixes: ed0ae3502fc9 ("net/bnxt: update ring group after ring stop start")
