Dave Hansen 9b9ac282ba x86/pkeys/selftests: Add a test for pkey 0 ...

[ Upstream commit 3488a600d9 ]

Protection key 0 is the default key for all memory and will
not normally come back from pkey_alloc().  But, you might
still want pass it to mprotect_pkey().

This check ensures that you can use pkey 0.
