Revert "Fix critical lens distortion bug in libmv after rB3a7d62cd1f5e."

This reverts commit 7e836bde11ce6521953c9f246cacd442a3ef6c0e.

Reverting the incomplete workaround, due to the following reasoning:

- There should be no dependency between CameraIntrinsics and the bundler
  code. This violates intended abstraction of the intrinsics class.

- The fix was not complete, or wrong. Even in the world where there is
  a requirement to the parameters storage size this should have applied
  to all distortion models, including Divisions, Nuke.

Proper fix will be committed next.
