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 4995f8ef, '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.
