don't use polling with new driver

With the 304.xx (API v5.0) drivers the cudaStreamSynchronize overhead
has been substantially reduced, so with these there is no need to switch
to polling. Additionally, with GPUs oversubscribed the polling has been
shown to be unstable, so this case is now detected and switch to polling
is not done.

Also corrected some warning/note printing layout.
