migration: Fix !replay_can_snapshot() error handling
Calling error_report() in a function that takes an Error ** argument
is suspicious. save_snapshot() and load_snapshot() do that, and then
fail without setting an error. Wrong. The HMP commands survive this
unscathed, since hmp_handle_error() does nothing when no error has
been set. Callers main() (on behalf of -loadvm) and
replay_vmstate_init() crash, but I'm not sure the error is possible
there.
Screwed up when commit 377b21ccea1 (v2.12.0) added incorrect error
handling right next to correct examples. Fix by calling error_setg()
instead of error_report().
