Grow: Do not try to restart if reshape is running
Grow process did not check if reshape is already started
when deciding about restarting.
Sync_action should be checked in this case, and if
reshape is running - restart flag should not be set.
Otherwise, Grow process will fail to write data to
sysfs, and reshape will not be continued.
