aarch64: Fix branch target to loop16
I goofed up when changing the loop8 name to loop16 and missed on out
the branch instance. Fixed and actually build tested this time.
* sysdeps/aarch64/memcmp.S (more16): Fix branch target loop16.
(cherry picked from commit 4e54d918630ea53e29dd70d3bdffcb00d29ed3d4)
