vc1dsp: Change remaining stride parameters to ptrdiff_t

The existing x86 assembly for loop filters uses the stride as a
full register without clearing/sign extending the upper half
of the registers on x86_64.

This avoids crashes if the caller would have passed nonzero bits
in the previously undefined upper 32 bits of the parameters.
