NFS: Allow the mount option retrans=0
We should allow retrans=0 as just meaning that every timeout is a major timeout, and that there is no increment in the timeout value. For instance, this means that we would allow TCP users to specify a flat timeout value of 60s, by specifying "timeo=600,retrans=0" in their mount option string.
