Virtualization - Mar 2010 - [PATCH 2/4] virtio: console: Fix early_put_chars usage

From: Francois Diakhate <fdiakh at gmail.com>

Currently early_put_chars is not used by virtio_console because it can
only be used once a port has been found, at which point it's too late
because it is no longer needed. This patch should fix it.
