Commit 7a7641063a (xfs/140: work with 64k
block size) created a test filesystem with AG size set to (8192 * block
size). When working with a 1k block sized XFS filesystem, this tries to
set the AG size to 8MiB which is less than the minimum AG size of
16MiB. Hence creation of the filesystem had actually failed.
This commit fixes the issue by resetting AG size to 16MiB if (8192 *
block size) results in a value less than 16MiB. Later the test file size
and the test file block count are then appropriately calculated.
