One usage of function domain_resume() is in domain resume domctl-op, and
the other is in domain_soft_reset(), which is already guarded with
CONFIG_MGMT_HYPERCALLS.
So we could wrap domain_soft_reset() with CONFIG_MGMT_HYPERCALLS.
Wrap XEN_DOMCTL_resumedomain-case transiently with CONFIG_MGMT_HYPERCALLS, and
it will be removed when introducing CONFIG_MGMT_HYPERCALLS on the
common/domctl.c in the last.
