sky2: remove restarting workaround flag
The whole restarting flag was introduced by Mike McCormack and was a temporary duct tape patch around issues with transmits inflight during restart. The problems it was covering are now fixed and the code should have been reverted. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>
