In md_check_recovery(), add clearing of all sync flags when sync is not
running. This fixes the issue where a sync operation is requested, then
'frozen' is executed before MD_RECOVERY_RUNNING is set, leaving stale
operation flags that cause subsequent operations to fail with EBUSY.

Merge into one with the previous fix patch. Do not introduce an issue
and fix it later.
