FIX: Set 'active' array state before array configuration

For not reshaped array in container during assembly array is in
auto-read-only state.  It is not possible to set disk slot for such
array and later reshape cannot be started also.  To move array from
'auto-read-only' to 'active' state storing 'active' state to sysfs is
added. This allows for disks configuration and reshape.

During reshaped array restart it is disabled by condition on restart
variable.

When reshape is starting, storing 'active' state to already active
array should not matter.
