DRI2: re-allocate DRI2 drawable if pixmap serial changes

If a pixmap header is modified or the drawable serial changes, some
aspects of the drawable are likely to have changed so we should
re-allocate the corresponding DRI2 drawable in that case.  This is one
way of catching when the root window pixmap changes through xrandr.
