NFSD: MKNOD should return NFSERR_BADTYPE instead of NFSERR_INVAL
A late paragraph of RFC 1813 Section 3.3.11 states: | ... if the server does not support the target type or the | target type is illegal, the error, NFS3ERR_BADTYPE, should | be returned. Note that NF3REG, NF3DIR, and NF3LNK are | illegal types for MKNOD. The Linux NFS server incorrectly returns NFSERR_INVAL in these cases.
