In function main(), remove rmdir in case if state == 'absent'.
Unmounting a file system should not lead to delete anything that is revealed after unmounting. 
Also, it leads to an error if a non empty directory is present under the ex-mountpoint after umount : [Errno 39] Directory not empty
So umount is successfull but the ansible run is failed. Of course, it is solved on second run.
