fjes: Fix unnecessary spinlock_irqsave
commit-bd5a256 introduces a deadlock bug in fjes_change_mtu(). This spin_lock_irqsave() is obviously unnecessary. This patch eliminates unnecessary spin_lock_irqsave() in fjes_change_mtu() Signed-off-by: Taku Izumi <izumi.taku@jp.fujitsu.com> Signed-off-by: David S. Miller <davem@davemloft.net>
