2020-09-17selftests/powerpc: ptrace-pkey: Don't update expected UAMOR valueAneesh Kumar K.V
commit 3563b9bea0ca7f53e4218b5e268550341a49f333 upstream. With commit 4a4a5e5d2aad ("powerpc/pkeys: key allocation/deallocation must not change pkey registers") we are not updating UAMOR on key allocation. So don't update the expected uamor value in the test.
