Nicholas Piggin b8e90cb7bc powerpc/64: Convert the syscall exit path to use RFI_TO_USER/KERNEL 
In the syscall exit path 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.
