So the version of the client you're using is sending
a trans2 call with level TRANSACT2_SETFILEINFO (0x8)- which
requires a 16-bit fnum, not a unicode path name.

The level required is TRANSACT2_SETPATHINFO (0x6)
as this sends a pathname.

Obviously if we have no pathname we can't do a
mknod call which requires a pathname argument.

This is a client bug of some kind - one I'm not
seeing in the latest CIFSFS client code.
