As recommended in "qapi/error.h", indicate success / failure with a
return value. Since ppc_set_compat() is called from a VMState handler,
let's make it an int so that it propagates any negative errno returned
by kvmppc_set_compat(). Do the same for ppc_set_compat_all() for
consistency, even if it isn't called in a context where a negative errno
is required on failure.
This will allow to simplify error handling in the callers.
