net/bnxt: fix jumbo frame configuration in firmware
In order to prevent reconfiguration of firmware resources for every
MTU change, configure FW with max MTU value using hwrm_func_cfg
to support all frame sizes. There is no need to overwrite the driver
level MTU variable data->mtu with the FW MTU.
Fixes: 905cd45ce30e ("net/bnxt: use configured MTU during load")
