    acpibat(4): Fix attach and detach ordering.

    On attach: Don't register acpibat_resume handler with pmf or
    acpibat_notify_handler with acpi until it is safe to call
    acpibat_update_info and acpibat_update_status.
    => This requires the sc->sc_sensor array to be allocated, so allocate
       that first.
    => This requires sc->sc_sme to be created, so defer them to
       config_interrupts after sysmon_envsys_register.
    => Make sure to register the notify handler before initially polling
       the info and status.

    On detach: Deregister pmf handler and acpi notifier before we destroy
    anything.
