The code in dri_make_current just checks the value of the pointers
to decide to update texture_stamp or not. This is buggy since a new
allocated drawable could share the same address with the previous
released drawable. Fix the stale pointer issue by always resetting
these pointers to NULL in dri_unbind_context.
v2:
Move the reset codes to the end of the function.
