If the nfs_acl program is available, Solaris clients expect both version
2 and version 3 to be available; RPC_PROG_MISMATCH leads to a mount
failure. Fake RPC_PROG_UNAVAIL when asked for nfs_acl version 2.
Trond has rejected this patch. I'm not sure how to deal with it in a
truly clean way, so probably I won't care and still use this as a vendor
patch.
