The value 0 for devs_max means to spread the allocated chunks over all
available devices, eg. stripe for RAID0 or RAID5. This got mistakenly
copied to the RAID1C3/4 profiles. The intention is to have exactly 3 and
4 copies respectively.
Fixes: 47e6f7423b91 ("btrfs: add support for 3-copy replication (raid1c3)")
Fixes: 8d6fac0087e5 ("btrfs: add support for 4-copy replication (raid1c4)")
