Issue

Creating aggregate with maxraidsize creates larger rg than maxraidsize.

Example:
storage aggregate create -aggregate aggr1 -maxraidsize 17 -node node1 -raidtype raid_dp -disklist 7.1.0,7.1.1,7.1.2,7.1.3,7.1.4,7.1.5,7.1.6,7.1.17,7.1.18,7.1.19,7.1.20,7.1.21,7.1.22,8.0.0,8.0.1,8.0.2,8.0.3,8.0.4,8.0.5,8.0.6,8.0.7,8.0.8,8.0.9,8.0.10,8.0.13,8.0.14,8.0.15,8.0.16,8.0.17,8.0.18,8.0.19,8.0.20,8.0.21,8.0.22
The above command successfully creates an aggregate but it includes incorrect raid groups like:

Aggregate aggr1 (online, raid_dp, fast zeroed) (block checksums) Plex /aggr1/plex0 (online, normal, active, pool0) RAID group /aggr1/plex0/rg0 (normal, block checksums) RAID Disk Device HA SHELF BAY
