    libxl: Resolve possible resource leak in dom0 maximum memory setting
    
    If either the "if (STRPREFIX(mem_tokens[j], "max:"))" is never entered
    or the "if (virStrToLong_ull(mem_tokens[j] + 4, &p, 10, maxmem) < 0)" break
    is hit, control goes back to the outer loop processing 'cmd_tokens' and
    it's possible that the 'mem_tokens' would be overwritten.
