net: FIX bonding sysfs rtnl_lock deadlock Sysfs files for a network device can not unconditionally take the rtnl_lock as the bonding sysfs files do. If someone accesses those sysfs files while the network device is being unregistered with the rtnl_lock held we will deadlock. So use trylock and restart_syscall to avoid this problem.
