Grow: Frozen array can't be idle 

When array is frozen but there is no recovery/reshape in mdstat,
check_idle() will not return error but grow countinue can still working.

Check is array frozen. Do not use sysfs sync_action parameter because it
doesn't exist for Raid0, simply check metadata_version in mdstat.
