s3: Fix async smb handling
In cli_echo with more than one response we ended up with more than one read_smb
request. One from the call to cli_smb_req_set_pending called from
cli_smb_received. The other one from cli_smb_received itself. I don't really
see another way to deal with this than to hold the read_smb request in the
cli_state.
Metze, please check!
