[PATCH] md/dm-raid: don't clear MD_RECOVERY_FROZEN after setting frozen

[linan666]

From: Li Nan <linan122@xxxxxxxxxx>

MD_RECOVERY_FROZEN should always remain set after array is frozen. But
in raid_message(), this flag is cleared soon after frozen. Fix it. This
flag will be cleared in md_idle_sync_thread(), there is no need to clear
it again for idle.

Fixes: cd32b27a66db ("md/dm-raid: don't call md_reap_sync_thread() directly")
