Fix LVM resize error due to fs utilities do not support renamed devices

As part of disk resize for microshift looks like there is bug in the
lvextend tool and it is not work when extending a lvm with resize.

- https://bugzilla.redhat.com/show_bug.cgi?id=2211856

This PR is a workaround which is provided as part of BZ where `lvextend`
shouldn't run with `-r` (resize) option. So now we are using `lvextend`
only for extending the respective logical volume and then using
`xfs_growfs` to grow that volume.
