Fix race between --create and --incremental
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.
