Don's try to restart dracut-initqueue if it's already there

Browse Source 
kdump's dump_to_rootfs will try to start initqueue unconditionally.
dump_to_rootfs will run after systemd isolate to emergency
target, so this is currently accetable.

But there is a problem when initqueue starts the emergency action
because of initqueue timeout. dump_to_rootfs will start initqueue and
lead to timeout again.

So following patch will remove the previous isolation wrapper, and
detect the service status here. Previous isolation makes the detection
impossible. Now this detection will be valid and helpful to prevent
double timeout or hang.
