mount_nfs.8: Update BUGS section for NFSv4.1/4.2
If the "intr" and/or "soft" mount options are used for NFSv4 mounts, the protocol can be broken when the operation returns without waiting for the RPC reply. The likelyhood of failure increases for NFSv4.1/4.2 mounts, since the session slot will be broken when an RPC reply is not processed. This is mentioned in the BUGS section of "man mount_nfs", but there was no specific mention of the session slot problem. This patch adds a sentence for this case.
