Fix VT_DISALLOCATE freeing an in-use virtual console, and fix a
use-after-free in vt_in_use().

Changed since v2:
    - Implemented tty_port_operations::destruct().
    - Added comments regarding vt_in_use() locking.

Changed since v1:
    - Made the vc_data be freed via tty_port refcounting.
    - Added patch to fix a use-after-free in vt_in_use().

  vt: vt_ioctl: fix use-after-free in vt_in_use()
