workaround=all no more recognize using fuse in fstab

In Ubuntu 18.04 we had this line in fstab which was working well

sshfs#dh@keewin:Mes_documents/ /home/dh/Mes_documents/ fuse compression=yes,port=36022,user,,noatime,reconnect,workaround=all 0 0

After upgrade to 20.04 we get

dh@feijoa:~$ mount /home/dh/Mes_documents/
unknown workaround: 'all'

If we replace all by eg. none it's OK

dh@feijoa:~$ lsb_release -rd
