Resolves kernel crash issue when a USB flash drive is inserted
into USB1 port with USB2 port configured as otg. Removing

Makes it possible to lock and unlock specific VTs.
When someone tries to switch to a locked vt, he gets redirected to VT 12.
We added the three cases VT_LOCK, VT_UNLOCK and VT_IS_LOCKED to vt_ioctl().
To indicate if a VT is locked we also added a flag to the struct vc_data.
