s3: smbclient: Stop an SMB2-connection from blundering into SMB1-specific calls.

Fix in the same way this was done in SMBC_opendir_ctx() for libsmbclient.
This fix means the admin no longer has to remember to set 'min client protocol ='
when connecting to an SMB2-only server (MacOSX for example) and trying to
list shares.
