net: add devm version of alloc_etherdev_mqs function
This patch adds devm_alloc_etherdev_mqs function and devm_alloc_etherdev
macro. These can be used for simpler netdev allocation without having to
care about calling free_netdev.
Thanks to this change drivers, their error paths and removal paths may
get simpler by a bit.
