Edward Adam Davis cc0bc4cb62 jfs: add sanity check for agwidth in dbMount ...

[ Upstream commit ddf2846f22e8575d6b4b6a66f2100f168b8cd73d ]

The width in dmapctl of the AG is zero, it trigger a divide error when
calculating the control page level in dbAllocAG.

To avoid this issue, add a check for agwidth in dbAllocAG.
