[PATCH blktests v2 4/4] common/xfs: check for max supported sector size

[Luis Chamberlain <mcgrof@kernel.org>]

mkfs.xfs will use the sector size exposed by the device, if this
is larger than 32k this will fail as the largest sector size on XFS
is 32k. Provide a sanity check to ensure we skip creating a filesystem
if the sector size is larger than what XFS supports.
