    hwasan: Remove testsuite check for a complaint message [PR112644]
    
    With recent updates to hwasan runtime libraries, the error reporting for
    this particular check is has been reworked.
    
    I would question why it has lost this message.  To me it looks strange
    that num_descriptions_printed is incremented whenever we call
    PrintHeapOrGlobalCandidate whether that function prints anything or not.
    (See PrintAddressDescription in libsanitizer/hwasan/hwasan_report.cpp).
    
    The message is no longer printed because we increment this
    num_descriptions_printed variable indicating that we have found some
    description.
    
    I would like to question this upstream, but it doesn't look that much of
    a problem and if pressed for time we should just change our testsuite.
    Bootstrapped Regtested on aarch64-none-linux-gnu and no issues.
