Don't pattern-init an unused variable that overallocates the stack
ART is intentionally walking to the stack top (lowest address), but the
pattern initialization is accidentally triggering a sanitizer failure
for an overflow. Removing the pattern initialization from that unused
(and uninitialized) variable restores the original functionality of
accessing every page of the available stack.
