net/bnxt: fix tunnel port accounting
Checks
Commit Message
Fix the tunnel port counting logic.
Currently we are incrementing the port count without checking
the if bnxt_hwrm_tunnel_dst_port_alloc would return success or failure.
Modify the logic to increment it only if the firmware returns success.
Fixes: 10d074b2022d ("net/bnxt: support tunneling")
