    tools/livepatch: initialise j to 0 to fix compilation error in gcc 4.5
    
    Initialise j to 0 to make some versions of gcc (e.g., gcc4.5/4.3) happy to
    avoid compilation error by commit beba3693f7243e68bbe31fe3794da91068eeea5b.
    
    Failure manifests with gcc 4.5 as:
    
    [  153s] cc1: warnings being treated as errors
    [  153s] xen-livepatch.c: In function 'main':
    [  153s] xen-livepatch.c:415:12: error: 'j' may be used uninitialized in 
this function
    [  153s] make[3]: *** [xen-livepatch.o] Error 1
