For a container, we only print an error log when the resource
charge fails. There may be some problems here:

1. If a large number of containers are created and deleted,
   there will be a lot of error logs.
2. According to an error log, we cannot better understand
   the actual pressure of resources.

Therefore, perhaps we should use a failcnt counter to count
the number of failures, so that we can easily understand the
actual pressure of resources and avoid too many error log..

v2: rename failcnt to nr_fails.
