i965: Initialize the intel_context::bufmgr pointer earlier.
This prevents a crash in a future patch.
_mesa_initialize_context() creates a default transform feedback object
by calling the NewTransformFeedbackObject() driver hook. Eventually,
we'll want to subclass that and allocate a buffer object. This means
passing brw->bufmgr to drm_intel_alloc_bo(), and crashing if it isn't
initialized yet.
The buffer manager is actually already initialized; we just hadn't
copied the pointer from intel_screen to intel_context quite early
enough.
