Michael Niedermayer 03f39fbb2a avcodec/x86/mlpdsp_init: Simplify mlp_filter_channel_x86()
Based on patch by Francisco Blas Izquierdo Riera
Commit message partly taken from carl

fixes a compilation
error in mlpdsp_init.c with -fstack-check and some gcc compilers (I
reproduced the issue with gcc 4.7.3) by simplifying the code.
