FIX: Do not allow for multiple reshape_array() execution during reshape_container() call

It can happen during reshape restart that reshape_array() can exit without
error (e.g. Grow.c:1915) and reshape is not moved to next array.
reshape_array() is called again for the same device.
Do not allow for such execution and check if last reshaped array is not
the current one.
This patch can be treat not as solution, but it allows for such errors
detection.
