vc: create vcs(a) devices for consoles
The buffer for the consoles are unconditionally allocated at con_init() time, which miss the creation of the vcs(a) devices. Since 2.6.30 (commit 4995f8ef9d3aac72745e12419d7fbaa8d01b1d81, 'vcs: hook sysfs devices into object lifetime instead of "binding"' to be exact) these devices are no longer created at open() and removed on close(), but controlled by the lifetime of the buffers.
