Suspend and crash dump operations can happen simultaneously
in case there is a FW assert during the suspend procedure
or when SSR calls all the devices crashdump callbacks.

To prevent that, a new flag is added, indicating that the
dumps collection is in progress, in order to allow the
suspend/reset decline if the dumps collection already started.
