Spapr capabilities are checked at machine init. If a capability cannot
be used, an error message is printed and QEMU exits. In most places,
the error message also contains an hint for the user. But we should
use error_append_hint() for that, as explained in the "qapi/error.h"
header.
This is already the case for cap_fwnmi_apply() and we now want to add
a similar check for nested KVM-HV. Unfortunately, spapr_caps_apply()
passes &error_fatal to all apply hooks and error_append_hint() is
never called.
So this reuses previous work from Vladimir Sementsov-Ogievskiy to
address that.
