xen: don't longjmp() after domain_crash() in check_wakeup_from_wait()

Continuing on the stack saved by __prepare_to_wait() on the wrong cpu
is rather dangerous.

Instead of doing so just call the scheduler again as it already is
happening in the similar case in __prepare_to_wait() when doing the
setjmp() would be wrong.
