    rombios/tcgbios: initialise logdataptr in HashLogEvent32
    
    Gcc complains:
    
    tcgbios.c: In function â??HashLogEvent32â??:
    tcgbios.c:1131:10: error: â??logdataptrâ?? may be used uninitialized in 
this function [-Werror=maybe-uninitialized]
        entry = tcpa_extend_acpi_log(logdataptr);
    
    It fails to figure out when logdataptr is used it is always initialised
    in a if block a few line above.
