[Ronald S. Bultje]

ffmpeg | branch: release/0.8 | Ronald S. Bultje <rsbultje at gmail.com> | Sun Jun 26 15:52:00 2011 -0700| [acf2d3293c305c96ac0afda28bd55233af4ce61c] | committer: Anton Khirnov

swscale: don't use planar output functions to write to NV12/21.

This prevents a crash when converting to NV12/21 without the bitexact
flags enabled.
(cherry picked from commit 0d994b2f45c08794899057ee7ca54f48218c0a53)
