can: Propagate SO_PRIORITY of raw sockets to skbs
This allows controlling certain queueing disciplines by setting the
socket's SO_PRIORITY option.
For example, with the default pfifo_fast queueing discipline, which
provides three priorities, socket priority TC_PRIO_CONTROL means
higher than default and TC_PRIO_BULK means lower than default.
