Chuck Lever 25ad5d6913 NFS: NFSERR_INVAL is not defined by NFSv2

[ Upstream commit 0ac903d1bf ]

A documenting comment in include/uapi/linux/nfs.h claims incorrectly
that NFSv2 defines NFSERR_INVAL. There is no such definition in either
RFC 1094 or https://pubs.opengroup.org/onlinepubs/9629799/chap7.htm

NFS3ERR_INVAL is introduced in RFC 1813.

NFSD returns NFSERR_INVAL for PROC_GETACL, which has no
specification (yet).

However, nfsd_map_status() maps nfserr_symlink and nfserr_wrong_type
to nfserr_inval, which does not align with RFC 1094. This logic was
introduced only recently by commit 438f81e0e9 ("nfsd: move error
choice for incorrect object types to version-specific code."). Given
that we have no INVAL or SERVERFAULT status in NFSv2, probably the
only choice is NFSERR_IO.

Fixes: 438f81e0e9 ("nfsd: move error choice for incorrect object types to version-specific code.")
