Surface: Initialize mAutoPrerotation

Hoping to fix the remaining buffer rejection issues. BBQ was
rejecting all buffers coming from a rotated app. The logs
indicated this was because Surface and BufferQueue
autoPreRotation state was mismatched, resulting
in BufferQueue dequeueing buffers of the wrong size.
