Eric W. Biederman b8afe64161 net-sysfs: Use rtnl_trylock in wireless sysfs methods. ...

The wireless sysfs methods like the rest of the networking sysfs
methods are removed with the rtnl_lock held and block until
the existing methods stop executing.  So use rtnl_trylock
and restart_syscall so that the code continues to work.
