The channel timeout ends up in a strange state during timeout handling
for a brief moment; it can become stopped and started again, and the
timeout lock is released in the middle. Add a more explicit rewind
function to reset the timeout to start if it's active. The active check
allows to use this from gk20a_channel_timeout_restart_all_channels(), so
that's also modified.
Also replace the return statements with more readable control flow in
gk20a_channel_timeout_handler().
