Pavel Skripkin b1c953dc85 tty: fix memory leak in vc_deallocate ... commit 211b4d42b70f1c1660feaa968dac0efc2a96ac4d upstream. syzbot reported memory leak in tty/vt. The problem was in VT_DISALLOCATE ioctl cmd. After allocating unimap with PIO_UNIMAP it wasn't freed via VT_DISALLOCATE, but vc_cons[currcons].d was zeroed.
