fbcon: when font is freed, clear also vc_font.data

    fbcon: don't lose the console font across generic->chip driver switch

uses a pointer in vc->vc_font.data to load font into the new driver.
However if the font is actually freed, we need to clear the data
so that we don't reload font from dangling pointer.
