lavr: x86: fix ff_conv_fltp_to_flt_6ch function prototypes
...
Changed to match the number of parameters in conv_func_interleave(), which is
how they are called. The change isn't strictly necessary because the 4th
parameter is not used, but the code is clearer if they match.

The current SSE version is slower than the MMX version on Athlon64 and Sandy
Bridge, but the SSE4 and AVX versions are faster on Sandy Bridge.

This would happen at least when lavr is used as a fifo with no
