Subject: MD: not clear ->safemode for external metadata array

From: Shaohua Li <shli@fb.com>

commit afc1f55ca44e257f69da8f43e0714a76686ae8d1 upstream.

->safemode should be triggered by mdadm for external metadaa array, otherwise
array's state confuses mdadm.

Fixes: 33182d15c6bf(md: always clear ->safemode when md_check_recovery gets the mddev lock.)
