arm64: uaccess cleanup macro naming

commit 7b90dc40 upstream

Now the uaccess primitives use LDTR/STTR unconditionally, the
uao_{ldp,stp,user_alternative} asm macros are misnamed, and have a
redundant argument. Let's remove the redundant argument and rename these
to user_{ldp,stp,ldst} respectively to clean this up.
