When outputting debug dump, print the contents of current push buffer
segment.
Also changes the debug dump to use pr_cont when applicable, and dumps
state before recovering in case channel was not loaded to an engine.

When aborting jobs on channel error situations, we manually set
the channel syncpoint's min == max in gk20a_disable_channel_no_update.
Nvhost will notice this manual syncpoint increment, and will call back
to gk20a_channel_update, which will clean up the job.
With semaphore synchronization, we don't have anybody calling back to
gk20a_channel_update, so we need to call it ourselves. Release job
semaphores (the equivalent of set_min_eq_max) on
gk20a_disable_channel_no_update, and if any semaphores were released,
call gk20a_channel_update afterwards.
Because we are actually calling gk20a_channel_update in some situations,
gk20a_disable_channel_no_update is no longer an appropriate name for the
function. Rename it to gk20a_channel_abort.

In error case we first disabled the channel, and reset sync point to
max. After this we set channel error state. This causes a race if
channel is closed between setting sync point and setting channel
state.
Rearrange the code so that error state is set first, and only then
channel is disabled.

On PBDMA error even though the engine might not be wedged, we need to
kick the channel out of engine. Add that logic. Also when channel is
not in engine, we need to remove it from runlist.

Even though we mask LBREQ interrupt, hardware will still indicate it
in PBDMA interrupt register. Stop treating LBREQ as fatal.

Lbreq interrupt can assert when there is memory back pressure. Do not
enable it as either stalling or nonstalling interrupt.
