GLOBAL had several meanings and is going away. In this patch, convert
all the inner function labels marked with GLOBAL to use SYM_INNER_LABEL
instead.
Note that retint_user needs not be global, perhaps since commit
2ec67971facc ("x86/entry/64/compat: Remove most of the fast system call
machinery"), where entry_64_compat's caller was removed. So mark the
label as LOCAL.
