tg3: Do not call device_set_wakeup_enable() under spin_lock_bh
The tg3 driver calls device_set_wakeup_enable() under spin_lock_bh,
which causes a problem to happen after the recent core power
management changes, because this function can sleep now. Fix this
by moving the device_set_wakeup_enable() call out of the
spin_lock_bh-protected area.
