[PATCH 1/2] Only pass --update=super-minor when activating v0 metadata md arrays.

[David Lehman <dlehman@xxxxxxxxxx>]

To minimize behavioral changes from 6.0 to 6.1 we track existing arrays'
metadata version so we know which ones can take --update=super-minor. In
Fedora we are discontinuing use of --update=super-minor.
