Adds missing comp_dev invalidation before accessing it.
We also need to move core check a little bit further,
since it also uses both comp_dev and pipeline objects.

Fixes very rare race condition, when multiple cores
schedule something in low latency scheduler. We should
allow for timer client to execute one more time after
being cancelled. There won't be any tasks on the list
to process, but at least we will stop everything
gracefully.

On exceptions and panics, the code will reach panic_rewind. That
function will, among the other things it needs to do to dump the info,
will also dump the exception cause (exccause register). This means that
normally coredumps from panics and those from exceptions are
indistinguishable.
In this commit I reserve the maximum value for exccause (63) to signify
that the dump actually came from a panic instead of a hardware
exception. The easiest way I could see that would not duplicate code is
to simply set the exccause register to this reserved value (otherwise it
could be undefined, as it's not initialized at boot).
I also update the core dumper tool to use 63 as the value reserved for
panics instead of 0 (which is IllegalInstructionCause, a valid hardware
exception).

Before the commit the C exception handler table was declared empty
(suspiciously). This also caused my own tests to fail to call the panic
code whenever an exception occurred.
This commit fixes this by actually declaring the slots themselves and
initializing them to xtos_p_none, and also setting the correct size
(64 * 4 instead of 0).

Draining task can take a long time depending
on various params. This patch disables system
agent which raises DSP PANIC in case firmware
is hanged. However draining task can look to
system agent in exactly the same manner thus
we disable it right before draining task and
reenable after draining is done.

This patch introduces and calulates draining intervals
