NFS: Allow text-based mounts via compat_sys_mount
The compat_sys_mount() system call throws EINVAL for text-based NFSv4 mounts. The text-based mount interface assumes that any mount option blob that doesn't set the version field to "1" is a C string (ie not a legacy mount request). The compat_sys_mount() call treats blobs that don't set the version field to "1" as an error. We just relax the check in compat_sys_mount() a bit to allow C strings to be passed down to the NFSv4 client.
