NFS: Handle a zero-length auth flavor list
Some releases of Linux rpc.mountd (nfs-utils 1.1.4 and later) return an
empty auth flavor list if no sec= was specified for the export. This is
notably broken server behavior.
The new auth flavor list checking added in a recent commit rejects this
case. The OpenSolaris client does too.
The broken mountd implementation is already widely deployed. To avoid
a behavioral regression, the kernel's mount client skips flavor checking
(ie reverts to the pre-2.6.32 behavior) if mountd returns an empty
flavor list.
