Noah Goldstein e3255e7d21 x86: Fix wcsnlen-avx2 page cross length comparison [BZ #29591] 
Previous implementation was adjusting length (rsi) to match
bytes (eax), but since there is no bound to length this can cause
overflow.

Fix is to just convert the byte-count (eax) to length by dividing by
sizeof (wchar_t) before the comparison.

Full check passes on x86-64 and build succeeds w/ and w/o multiarch.

(cherry picked from commit b0969fa53a)
