Hmm, since nfs_fs_mount is now shared between nfs23 and nfs4, a better
"revert" is probably this one:

Subject: [PATCH] Revert "NFS: Let mount data parsing set the NFS version"
This reverts commit db8333519187d5974cf2ff33910c893bf8727d9f.
The original commit message says, that the version field is
"unconditionally set while parsing mount data".
Unfortunatly this is not the case and the version field may
stay 0 so that nfs_init_server returns -EPROTONOSUPPORT
causing the mount to fail. Reverting this commit fixes the
issue.
