aarch64/strcmp: fix misaligned loop jump target
I accidentally set the loop jump back label as misaligned8 instead of
do_misaligned. The typo is harmless but it's always nice to not have
to unnecessarily execute those two instructions.
* sysdeps/aarch64/strcmp.S (do_misaligned): Jump back to
do_misaligned, not misaligned8.
(cherry picked from commit 6ca24c43481e2c93a6eec362b04c3e77a35b28e3)
