nfs4_setfacl had the possibility to use an optional index
to add/remove an ACL entry.
This was causing some confusion as numeric files could be interpreted
as indexes.
This change adds an extra command line option '-i' to specifically
handle the indexes.
The index can be used only with certain operations (add and remove).
The new syntax, when using indexes, would be:
~]# nfs4_setfacl -i 3 -a A::101:rxtncy file123
