[PATCH] ARM: don't export unused return_address()

Without the frame pointer enabled, return_address() is an inline
function and does not need to be exported, as shown by this warning:

WARNING: "return_address" [vmlinux] is a static EXPORT_SYMBOL_GPL

Move the EXPORT_SYMBOL_GPL() into the #ifdef as well.
