    rombios/tcgbios: initialise size in tcpa_extend_acpi_log
    
    Gcc complains:
    
    tcgbios.c:362:3: error: â??sizeâ?? may be used uninitialized in this 
function [-Werror=maybe-uninitialized]
       memcpy((char *)lasa_last, (char *)entry_ptr, size);
    
    It fails to figure out if size is used in memcpy it is always initialised.
