    global: drop incorrect memset
    
    shell_global_get_memory_info tries to zero initialize the output
    parameter with memset, but it passes the wrong size (because of
    a missing *).  There's no reason to do the memset, though. In the
    normal case all members of the struct gets initialized before the
    function returns anyway.
    
    This commit drops the memset call in favor of one explicit 0 assignment
    that only gets executed on on atypical platforms.
