Log: If a "principal" argument isn't provided for a Kerberized NFS mount, the kernel would generate a bogus one with a ":/<path>" suffix. This would only occur for the case where there was no explicit "principal" argument and the getaddrinfo() call in mount_nfs.c failed to a return a cannonical name for the server. This patch fixes this unusual case.
