vbo: Move no_current_update out of _mesa_prim.

The _mesa_prim::no_current_update flag should tell the compiled
display list if the current attributes that are placed in the dlists
vbo shall take a defined state past replay of a display list.
Immediate mode draws compiled into display lists should set the
current values. Array draws may leave the current values in
undefined state.
So finally this flag is not a property of every primitive
but it is a property of the compiled display list and there it
is a property of the last primitive compiled into the list.
So move the flag out of _mesa_prim into vbo_save.
