net/sfc: support more options for a number of Rx descriptors

The number of Rx descriptors is not used as HW Rx ring size any more.
It simply defines maximum fill level.

net/sfc: fix main MAC address handling

There is a school of thought that rte_eth_dev_default_mac_addr_set()
must call the PMD callback first and then save the new MAC address
in dev->data->mac_addrs[0]. If this concept gets approved, it will
break the current approach used in sfc driver as the latter relies
on the assumption that the new MAC address is already contained in
dev->data->mac_addrs[0], and, if adapter restart is needed to make
the HW apply the new address, the outdated value will be retrieved
from dev->data. In order to preclude any possible bugs, this patch
adds device private storage for the up-to-date copy of the address.

ethdev: add return value to stats get dev op

The stats_get dev op API doesn't include return value, so PMD cannot
return an error in case of failure at stats getting process time.

Since PCI devices can be removed and there is a time between the
physical removal to the RMV interrupt, the user may get invalid stats
without any indication.

This patch changes the stats_get API return value to be int instead of
void.

All the net PMDs stats_get dev ops are adjusted by this patch.
