Align various point_get_affine_coordinates implementations.

The P-224 implementation was missing the optimization to avoid doing
extra work when asking for only one coordinate (ECDH and ECDSA both
involve an x-coordinate query). The P-256 implementation was missing the
optimization to do one less Montgomery reduction.
