aarch64: h264dsp: Remove unnecessary sign extensions
These became unnecessary when the stride arguments were changed from
int to ptrdiff_t in bc26fe89275c267d169b468356c82ee59874407d
(0576ef466d8a631326d1d0a5ec2e4c4c81d25353) and
d5d699ab6e6f8a8290748d107416fd5c19757a1b
(aa844dc46f93182a63ec0b53267d19e7342c79b9).
