Please cite the appropriate parts of the RFC. It seems to be RFC 3530.
| 14.1. Procedure 0: NULL - No Operation
| SYNOPSIS
| <null>
| ARGUMENT
| void;
| RESULT
| void;
| DESCRIPTION
| Standard NULL procedure. Void argument, void response. This
| procedure has no functionality associated with it. Because of
| this it is sometimes used to measure the overhead of processing a
| service request. Therefore, the server should ensure that no
| unnecessary work is done in servicing this procedure.
| ERRORS
| None.
According to this, a response to a NULL request simply must not return
an authentication error. Also no erata exists for this part.

You saw that the versions of the ones with the behaviour are strictly
higher then the others?
Please fix your MUA, it produces too long lines, and ask on
linux-nfs@vger.kernel.org.
