Subject: md-cluster: fix wrong condition check in raid1_write_request
From: Guoqing Jiang <gqjiang@xxxxxxxx>
[ Upstream commit 385f4d7f946b08f36f68b0a28e95a319925b6b62 ]
The check used here is to avoid conflict between write and
resync, however we used the wrong logic, it should be the
inverse of the checking inside "if".
Fixes: 589a1c4 ("Suspend writes in RAID1 if within range")
