This modifies locking in Create to eliminate a situation where
--incremental can assemble a device between write_init_super() and
add_disk(), which causes Create to fail.
It sporadically occurs e.g. when metadata is written on a device,
causing an udev change event which triggers mdadm --incremental.

Thanks for the patch.
I've taken the liberty of changing it a little. I didn't like the fact that
we dropped the lock and then took it again. It probably doesn't matter, but
it feels cleaner to hold it the whole time.
So this is the result. Let me know if you disagree at all.
Hello Neil,
Your changes are OK, thanks.
Regards,
Artur
