console: Allow using vprintk() with disabled console
The prototype of vprintk() is currently declared unconditionally, which
prevents it from being used in situations where the console is disabled.
The code will compile correctly, but not link, since the definition in
console.c isn't being provided. This adds a shim around the declaration
so that, like printk(), a call to vprintk() in this situation will expand
to a no-op function instead.
