setarch: differentiate between "unrecognized" and "cannot set"

When the provided string does not match any architecture that
setarch knows about, the response stays "Unrecognized architecture",
but when trying to set the specified architecture does not have any
effect, then respond with "Kernel cannot set architecture to...".
