md: don't clear MD_RECOVERY_FROZEN for new dm-raid until resume
After commit 9dbd1aa3a81c ("dm raid: add reshaping support to the
target") raid_ctr() will set MD_RECOVERY_FROZEN before md_run() and
expect to keep array frozen until resume. However, md_run() will clear
the flag by setting mddev->recovery to 0.
Before commit 1baae052cccd ("md: Don't ignore suspended array in
md_check_recovery()"), dm-raid actually relied on suspending to prevent
starting new sync_thread.
Fix this problem by keeping 'MD_RECOVERY_FROZEN' for dm-raid in
md_run().
Fixes: 1baae052cccd ("md: Don't ignore suspended array in md_check_recovery()")
Fixes: 9dbd1aa3a81c ("dm raid: add reshaping support to the target")
