[PATCH] nfsacl: Solaris VxFS compatibility fix

Here is a compatibility fix between Linux and Solaris when used with VxFS
filesystems: Solaris usually accepts acl entries in any order, but with
VxFS it replies with NFSERR_INVAL when it sees a four-entry acl that is not
in canonical form.  It may also fail with other non-canonical acls -- I
can't tell, because that case never triggers: We only send non-canonical
acls when we fake up an ACL_MASK entry.

Instead of adding fake ACL_MASK entries at the end, inserting them in the
correct position makes Solaris+VxFS happy.  The Linux client and server
sides don't care about entry order.  The three-entry-acl special case in
which we need a fake ACL_MASK entry was handled in xdr_nfsace_encode.  The
patch moves this into nfsacl_encode.
