am-utils-6.2 - fix NFSv3 access method return on non-existent mount point

From: Ian Kent <raven@themaw.net>

When the NFS v3 access method is called and there is no mount point
corresponding to the path ESTALE needs to be returned the kernel NFS
client so an NFS lookup will be done and the mount point re-mounted.

If there is no map entry to mount the NFS v3 lookup method can then
return the failure.
