net/mlx4_en: Refactor mlx4_en_free_tx_desc
Some code re-ordering, functionally equivalent.
- The !tx_info->inl check is evaluated anyway in both flows
(common case/end case). Run it first, this might finish
the flows earlier.
- dma_unmap calls are identical in both flows, get it out
of the if block into the common area.
Performance tests:
Tested on ConnectX3Pro, Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz
Gain is too small to be measurable, no degradation sensed.
Results are similar for IPv4 and IPv6.
