Update pending buffer counts immediately
Increment any buffer updates in the binder thread so systrace
has an accurate idea of when the buffers arrived on the server.
The buffer count will continue to be dropped when the buffers
are dropped or latched in the main thread.
Test: capture systrace and check pending buffer counts
