There are several dumping flows in the driver in case of a fail prior to operational. In some cases we get 2 dumps while in others we get none. Fix this by uniting the different flows. Add a different dump type to driver triggered dumps in case we want a dump but did not got assert, and make all dumping go through iwl_fw_dbg_collect_desc to avoid multiple dumps.
