RHEL8.0: xfs_growfs and xfs_info no longer support a device path but require a mount point

Issue

• Change in behaviour of xfs_growfs and xfs_info
• These XFS utilities previously supported device names of block devices that could be found in the mount table
• Changes in 8.0 and 8.1 now are in line with the intended function
• As a result, the Ansible filesystem module resizing of XFS fails when presented with the device name as it requests
• The -n option of xfs_growfs no longer works with the device name
