bnge: fix reserving resources from FW

2026-02-26T22:59:40Z

[ Upstream commit 604530085b2ef484843c723a105b6fd3218b4710 ] HWRM_FUNC_CFG is used to reserve resources, whereas HWRM_FUNC_QCFG is intended for querying resource information from the firmware. Since __bnge_hwrm_reserve_pf_rings() reserves resources for a specific PF, the command type should be HWRM_FUNC_CFG.
