Ensure we mark windows as not seamlessly rotating when removing them.

Otherwise we fail to reach mSeamlessRotationCount = 0, this used
to not be a problem however now that we use the mSeamlesslyRotated
state based on it, it causes the system to believe we are still
seamlessly rotating and refuse to perform new rotation animations.
