net/bnxt: fix VFR cleanup during init failure

If VF-rep port add fails for some reason, code was rolling back
all ports added so far. With some applications, there is no need
to do that. Just log failure message for the VF rep port add and
continue.
Also include RTE_MAX_ETH_PORTS value in the bounds check as one port
will be taken by the uplink port anyway
