intel: make intel_flush_front safe to call during initial MakeCurrent
The patch that follows will fix a bug that prevents
intel_flush_front() from being called often enough. In doing so, it
will create a situation where intel_flush_front() is called during the
initial call to glXMakeCurrent(). In this circumstance,
ctx->DrawBuffer hasn't been initialized yet and is NULL. Fortunately,
intel->front_buffer_dirty is false, so intel_flush_front() doesn't
actually need to do anything. To avoid a segfault, swap the order of
terms in intel_flush_front()'s if statement.
