Fix the issue where the kernel poll code would place the tracking struct on the caller stack and share it with other threads, thus creating a cache coherence issue on systems where KERNEL_COHERENCE is enabled. This works by eliminating the thread backpointer in struct _poller and simply placing the (now just two-byte!) struct directly into the thread struct. Note that this doesn't attempt to fix the API paradigm that the natural way to structure a call to k_poll() is to use an array of k_poll_events on the CALLER's stack. So it's likely that most "typical" k_poll code is still going to have problems with KERNEL_COHERENCE. But at least now the kernel internals aren't fundamentally broken.
