  From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>

Added an invalid fw_grp_id check inside bnxt_hwrm_ring_grp_free().
This will prevent invalid fw_grp_id to be passed to the FW which can
result in an error.
This fixes the following failure in the "port stop" -> "port start"
sequence:

bnxt_hwrm_ring_grp_free(): error 2:0:00000000:0204
bnxt_hwrm_ring_grp_free(): error 2:0:00000000:0204

Fixes: 5803d86b87df ("net/bnxt: update ring group after ring stop start")
