Staging: wlan-ng: block ioctls until card fully initialised
Add a mutex to block ioctls before the card is fully initialised and
only allow one ioctl at a time.
This stops udev trying to load the firmware before to card is fully up.
patch ported from wlan-ng-devel
Karl Relton <karllinuxtest.relton@ntlworld.com> spotted that this was
missing from the staging version,
