Incorrect error returned on setting file compressed on SMB2
When the server (for an SMB2 or SMB3 mount) doesn't support an ioctl (such as setting the compressed flag on a file) we were incorrectly returning EIO instead of EOPNOTSUPP, this is confusing e.g. doing chattr +c to a file on a non-btrfs Samba partition, now the error returned is more intuitive to the user. Also fixes error mapping on setting hardlink to servers which don't support that. Signed-off-by: Steve French <smfrench@gmail.com> Reviewed-by: David Disseldorp <ddiss@suse.de>
