Revert "Revert "Improve SIMD of av1_compute_stats_avx2()""

This reverts commit f38717653c29dc5648a1dd7ab8f8639c0cbdcb2e.

Reason for revert: Valgrind failures
The issue was occurring due to the 256 bits load from an
unintialized buffer when loop Restoration unit width is
not a multiple of 16. This CL resolves this issue by doing
memset() for the extra row.
