[PATCH] tty/vt: Remove printable variable

From: Daniel Vetter
Date: Fri Aug 26 2022 - 16:24:29 EST


Every since the 0.99.7A release when console_register() was introduced
it's become impossible to call vt_console_print (called
console_print() back then still) directly. Which means the
initialization issue this variable protected against is no more.

Give it a send off with style and let it rest in peace.
