    addressbook: Fix ordering of parameters to fread()
    
    This is a follow up to commit 2a5d6db6, since it did not eliminate the
    use of tainted data in the sense that fread() was being called with a
    variable-sized size argument, when it should be called with a
    variable-sized nmemb argument.
    
    Coverity issue: #1061517
