fix: array is reassembled inactive if stopped during resync 

If initial resync or recovery of a redundant array is not finished
before it is stopped then during assembly md will start it as inactive.
Writing readonly to array_state in assemble_container_content
fails because md thinks the array is during reshape.

In fact we only have a reshape if both current and previous map
states are the same. Otherwise we may have resync or recovery.
Setting reshape_active in such cases causes the issue.
