s3-client: smbclient shows no error if deleting a directory with del failed

BUG: https://bugzilla.samba.org/show_bug.cgi?id=10260

In SMB1 the server filters by attribute requested, in SMB2 there is
no attribute sent. Emulate this on the client to provide the same
ABI to callers.

In SMB1 the server returns NT_STATUS_NO_SUCH_FILE if FindFirst
finds no files. Emulate this on the client.
