dm-raid: don't set io_min and io_opt for raid1
These commands
modprobe brd rd_size=1048576
vgcreate vg /dev/ram*
lvcreate -m4 -L10 -n lv vg
trigger the following warnings:
device-mapper: table: 252:10: adding target device (start sect 0 len 24576) caused an alignment inconsistency
device-mapper: table: 252:10: adding target device (start sect 0 len 24576) caused an alignment inconsistency
The warnings are caused by the fact that io_min is 512 and physical block
size is 4096.
If there's chunk-less raid, such as raid1, io_min shouldn't be set to zero
because it would be raised to 512 and it would trigger the warning.
