egl_dri2: Fix one context, multiple surfaces.
When a context was made current to another surface, the old code did
this
dri2_dpy->core->bindContext(cctx, ddraw, rdraw);
dri2_dpy->core->unbindContext(old_cctx);
and there will be no current context due to the second line.
unbindContext should be called only when bindContext is not. This fixes
a regression since d19afc57. Thanks to Neil Roberts for noticing the
issue and creating a test case.
