Adopt the same approach as in intel_graphics_quirks(), with a static
local variable, to control when the quirk has already been applied.
However, contrary to intel_graphics_quirks(), here we always set it as
applied as soon as it's called to avoid changing the current behavior
that is not failing.
This is the last user of the flags, so we can cleanup the early-quirks,
removing all the flags logic later.
