The selection of Rx/Tx handlers is done at several places,
group them in one function set_rxtx_funcs().
The update of hw->use_simple_rxtx is also rationalized:
- initialized to 1 (prefer simple path)
- in dev configure or rx/tx queue setup, if something prevents from
using the simple path, change it to 0.
- in dev start, set the handlers according to hw->use_simple_rxtx.

In rx/tx queue setup functions, some code is executed only if
use_simple_rxtx == 1. The value of this variable can change depending on
the offload flags or sse support. If Rx queue setup is called before Tx
queue setup, it can result in an invalid configuration:
- dev_configure is called: use_simple_rxtx is initialized to 0
- rx queue setup is called: queues are initialized without simple path
support
- tx queue setup is called: use_simple_rxtx switch to 1, and simple
Rx/Tx handlers are selected
Fix this by postponing a part of Rx/Tx queue initialization in
dev_start(), as it was the case in the initial implementation.
