arm64: ftrace: always pass instrumented pc in x0
The core ftrace hooks take the instrumented PC in x0, but for some
reason arm64's prepare_ftrace_return() takes this in x1.
For consistency, let's flip the argument order and always pass the
instrumented PC in x0.
There should be no functional change as a result of this patch.
