powerpc/64: Convert fast_exception_return to use RFI_TO_USER/KERNEL Similar to the syscall return path, in fast_exception_return we may be returning to user or kernel context. We already have a test for that, because we conditionally restore r13. So use that existing test and branch, and bifurcate the return based on that.
