Alexey Kardashevskiy 67697026c0 KVM: PPC: Inform the userspace about TCE update failures
[ Upstream commit f7960e299f13f069d6f3d4e157d91bfca2669677 ]

We return H_TOO_HARD from TCE update handlers when we think that
the next handler (realmode -> virtual mode -> user mode) has a chance to
handle the request; H_HARDWARE/H_CLOSED otherwise.

This changes the handlers to return H_TOO_HARD on every error giving
the userspace an opportunity to handle any request or at least log
them all.
