avcodec/aarch64/neon.S: Update neon.s for transpose_4x4H
The transpose_4x4H is wrong which cost me much time to find this bug. The orders of r2 and r3 are wrong,
this bug waste me much time while I make aarch64 arm instruction which used the function.
(cherry picked from commit c18176bd551b4616757080376707637e30547fd0)
