[PATCH 3/3] binder: filter out nodes when showing binder procs

When dumping out binder transactions via a debug node,
the output is too verbose if a process has many nodes.
Change the output for transaction dumps to only display
nodes with pending async transactions.

Signed-off-by: Todd Kjos <tkjos@xxxxxxxxxx>
v2: no change, just resubmitted as #3 of 3 patches instead of by itself
There is no actual dependancy on patches 1 and 2 of the series
