btrfs-progs: remove btrfs_raid_profile_table

For SINGLE and DUP RAID profiles we can get the num_stripes values from
btrfs_raid_attr::dev:stripes. For all other RAID profiles the value is
calculated anyways.

As this was the last remaining member of the btrfs_raid_profile_table we
can remove it as well.
