Subject: [PATCH net] bnxt_en: Fix compile error regression when CONFIG_BNXT_SRIOV is not set

bp->sriov_cfg is not defined when CONFIG_BNXT_SRIOV is not set.  Fix
it by adding a helper function bnxt_sriov_cfg() to handle the logic
with or without the config option.

Fixes: 46d08f55d24e ("bnxt_en: extend RTNL to VF check in devlink driver_reinit")
