[SNMP4J] Prevent access with VacmMIB

[Frank Fock]

Hi Matthieu,

When the view name is a zero length string then access is not allowed
due to the following code in isAccessAllowed(..)

...
     if (viewName == null) {
       return VACM.VACM_NO_ACCESS_ENTRY;
     }
     if (viewName.length() == 0) {
       return VACM.VACM_NO_SUCH_VIEW;
     }
...

Best regards,
Frank
