dm raid1: keep issuing IO after leg failure
Currently if there is a leg failure, the bio will be put into the hold
list until userspace does a remove/replace on the leg. Doing so in a
cluster config (clvmd) is problematic because there may be a temporary
path failure that results in cluster raid1 remove/replace. Such
recovery takes a long time due to a full resync.
Update dm-raid1 to optionally ignore these failures so bios continue
being issued without interrupton. To enable this feature userspace
must pass "keep_log" when creating the dm-raid1 device.
