    blktap2: initialise buf in qcow2raw.c:main
    
    Gcc complains:
    
    qcow2raw.c: In function â??mainâ??:
    qcow2raw.c:387:17: error: â??bufâ?? may be used uninitialized in this 
function [-Werror=maybe-uninitialized]
        treq.buf     = buf;
                     ^
    
    But buf is a valid buffer allocated by posix_memalign at that point.
