Correct allowed raid levels on balance. Raid5 with 3 devices is well defined while the old logic allowed raid5 only with a minimum of 4 devices when converting the block group profile via btrfs balance. Creating a raid5 with just three devices using mkfs.btrfs worked always as expected. This is now fixed and the whole logic is rewritten.
