[PATCH 1/9] FIX: Do not configure and start, already started reshape

[Adam Kwolek <adam.kwolek@intel.com>]

When Grow_continue() calls reshape_array(), reshape is configured
and it is started with array. We cannot start reshape again,
when reshape is in progress.
/it in fact waits due to array_state == 'readonly'/
