Henrik Gramner aa751573fe avcodec/h264: Fix segfault in 4:2:2 chroma deblock with 32-bit msvc 
Using rNm and x86inc's stack allocation with a negative value at the same
time isn't supported, and caused the original stack pointer to be clobbered
when using a compiler that doesn't support stack alignment.
