Bug 630092 - Coverity #15479: Resource leaks issues
    
    https://bugzilla.redhat.com/show_bug.cgi?id=630092
    
    Description:
    
    The mep_pre_op() is correctly allocating and releasing smods during
    modify operation. However, the "else" clause on line 1517 theoretically
    allows other operations to enter and cause resource leak. The code has
    been modified to reject other operations from operating against the
    config entries.
