[RFC PATCH 2/7] virtio: use pr_debug_ratelimited to avoid flooding

[Jim Cromie <jim.cromie@gmail.com>]

When I test dynamic-debug's static-key toggling performance in a
virtme-ng session, it is too easy to create an enormous flood of
printks to the console.

  #> echo +p > /proc/dynamic_debug/control
  #> echo -p > /proc/dynamic_debug/control

Now theres no "good reason" to shoot your own foot, but this is also
easy to fix, by ratelimiting the sources of the flood.  I don't think
theres a loss of utility to virtio.

Example console output is below the snip.  For this test-case,
ratelimiting suppresses >900k callbacks.  It also allows this simple
load test for the static-key toggling performance in a following patch.
