Create: over-ride "start_ro" setting when creating an array. 

If module parameter start_ro is set, arrays start readonly.
This is OK when assembling, but is very surprising when creating
an array as the resync won't start.
So over-ride the setting (unless --read-only was given) make
arrays RW when created.
