Update a comment on the nonexistent vpx_codec_init() function. Replace it
with vpx_codec_dec_init() and vpx_codec_enc_init().
I missed this comment in the last commit.

/*!\brief init function pointer prototype
*
* Performs algorithm-specific initialization of the decoder context. This
- * function is called by the generic vpx_codec_init() wrapper function, so
+ * function is called by vpx_codec_dec_init() and vpx_codec_enc_init(), so
* plugins implementing this interface may trust the input parameters to be
* properly initialized.
