Kernel: Tidy up debug logging a little bit

Browse source 
When using dbg() in the kernel, the output is automatically prefixed
with [Process(PID:TID)]. This makes it a lot easier to understand which
thread is generating the output.

This patch also cleans up some common logging messages and removes the
now-unnecessary "dbg() << *current << ..." pattern.
