[CRIU] [PATCH 1/3] log: Add pr_quelled helper

[Cyrill Gorcunov]

If we need to check if current loglevel will suppress
our messagess (say you need to run pr_debug in a cycle)
we can use this helper to eliminate unneded calls.

Like
  if (!pr_quelled(LOG_DEBUG)) {
    ... do something specific to LOG_DEBUG ...
  }
