qa/cephfs: fix TestRenameCommand and unmount the clinet before failing fs

We should else bring and wait for MDS to be up since it is needed
for unmounting of CephFS in CephFSTestCase.tearDown() to be successful,
or just unmount the mountpoints before failing the filesystem.

Since the mountpoint won't be used in later tests so we just unmount
it.
