[PATCH] kNFSd: Use only the uid when deciding whether a setclientid is being done with the "same principal".

From: NeilBrown <neilb@cse.unsw.edu.au>

I would have assumed that we should also check for the same security
(pseudo)flavor, but that doesn't seem to be how Solaris does it, and since
the spec doesn't suggest including such information in the clientid, that
would make it impossible to switch pseudoflavors.
