[Crash-utility] log -T option should not be support after system suspend

Hello,list I notice a new option about "log -T",which translates the leading timestamp value of each message into human readable format.​i have checked the code,the implementation mainly consists of two steps: 1.use "kt->boot_date.tv_sec=kt->date.tv_sec - uptime_sec" to get system bootup time,uptime_sec is come from jiffies 2.use "kt->boot_date.tv_sec + nanos" to translates readable timestamp in every log entry. This change does not take into account the system sleep,once system suspend this translation will make error,printk timestamp and jiffies won't be update during suspend,and system suspend is a common feature,so i think change is a bug. As far as i know​ we can’t get the correct conversion time once the system sleeps.so we have to restrict​ this option only work in non-suspend state. patch is attached. wrong log:​ [Thu May 7 03:27:38 2020] PM: suspend entry 2020-05-06 19:22:40.481371186 UTC [Thu May 7 03:27:38 2020] PM: suspend exit 2020-05-06 19:22:49.168938838 UTC ...
