log: mute messages generated by log drivers
When a message is written by a log driver (e.g. via the network stack) this
may result in the generation of further messages. We cannot allow these
additional messages to be emitted as this might result in an infinite
recursion.
Up to now only the syslog driver was safeguarded. We should safeguard all
log drivers instead.
