fonts: Do not unload completely on USB.
The font engine can now perform cache lookups even if the font file is
closed, if the font was disabled with the new font_disable_all() function.
It is highly probable that the lookup succeeds but in the cache-miss case
a blank, full-width glyph will be returned.
