vc: create vcs(a) devices for consoles

[Kay Sievers]

Subject: 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, these devices are no longer created at open()
and removed on close(), but controlled by the lifetime of the
buffers.
