tty: vt, return error when con_startup fails
[ Upstream commit 6798df4c5fe0a7e6d2065cf79649a794e5ba7114 ]
When csw->con_startup() fails in do_register_con_driver, we return no
error (i.e. 0). This was changed back in 2006 by commit 3e795de763.
Before that we used to return -ENODEV.
So fix the return value to be -ENODEV in that case again.
Fixes: 3e795de763 ("VT binding: Add binding/unbinding support for the VT console")
