[PATCH] nfsroot: do not silently stop parsing on an unknown option

It would be helpful if the kernel did not silently stop parsing
nfs options, but instead warned about any he does not recognize. The
attached patch adds one printk to do just that.

It took me a couple of hours to find my configuration mistake.
