mips: Fix potential illegal instruction error.
MSA2 optimizations are attached to MSA macros in generic_macros_msa.h. It's difficult to do runtime check for them. Remove this part of code can make it more robust. H264 1080p decoding: 5.13x==>5.12x. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
