[PATCH 07/19] mdadm/tests: 03assem-incr enhance

[Xiao Ni <xni@redhat.com>]

It fails when hostname lenght > 32. Because the super1 metadata name
doesn't include hostname when hostname length > 32. Then mdadm thinks
the array is a foreign array if no device link is specified when
assembling the array. It chooses a minor number from 127.
