MTL C0 stepping fixed issue related to butrress interrupt status clearing,
to clear an interrupt status it is required to write 1 to specific
status bit field. This allows to execute read, modify and write routine.

Writing 0 will not clear the interrupt and will cause interrupt storm.

<title>accel/qaic: Fix NULL pointer deref in qaic_destroy_drm_device()</title>

<content type='text'>
If qaic_destroy_drm_device() is called before the device has fully
initialized it will cause a NULL pointer dereference as the drm device
has not yet been created. Fix this with a NULL check.

<title>accel/qaic: Free user handle on interrupted mutex</title>

After user handle is allocated, if mutex is interrupted, we do not free
the user handle and return an error. Kref had been initialized, but not
added to users list, so device teardown would also not call free_usr.

In order to increase reliability of the event queue interface,
we apply to Gaudi2 the same mechanism we have in Gaudi1.
The extra validation is basically checking that the received
event index matches the expected index.
