In the following scenario:
- CreateContext C1
- MakeCurrent C1
- DestroyContext C1 (does not actually destroy the first context, postponed
until the next MakeCurrent)
- CreateContext C2
- MakeCurrent C2
MakeCurrent will call flush on a context which might not even have had a front
buffer, leading to crashes. Since none of the dri drivers use the flush in
their unbind_context implementation either, we remove this useless flush front
call.
This fixes GPU crashes with Chrome and gallium drivers.
