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.
