part 2/2 of fixing Altivec-accelerated H264 luma inloop filter

In h264_deblock_q1, the result of the deblock needs to be kept to
be used in future deblocks, so return this value now.

Also change the sign of tc0 vector: It is really a signed value, so
treat it as such until after the >=0 check;...
