Hey Trond,

Attached is a patch that changes nfs_sb_init() to returned correct
errno (when nfs_get_root() fails), instead of returning a static
errno of -EINVAL.  By returning the correct errno, it allows
the mount command to print the correct error message.
For example,  currently when you try to mount a v4 fs that
is not exported on the server you get:

    Lucky# mount -v -t nfs4  harryp:/home /mnt/harryp
    mount: wrong fs type, bad option, bad superblock on harryp:/home,
           or too many mounted file systems

With this patch, error message becomes:

    Lucky# mount -v -t nfs4  harryp:/home /mnt/harryp
    mount: special device harryp:/home does not exist

Now that the mount command correctly decipher the errror
I also changed two hard coded printk into dprintks to cut
down on the number of messages (from 4 to 2) that are logged
for this type of error.
