Fix T66529: Cycles motion blur render errors with fast rotating objects

In transform_motion_decompose, successive quaternion pairs are checked to be
aligned such that their interpolation is rotation through the shortest angle
between them. If not, the first in the pair was flipped. This can cause
problems for sequences of more than 2 quarternions, since flipping the first
in a pair might misalign the previously pair, if unlucky.

Instead, this change flips the second in the pair, which is safe when
iterating forwards.
