Separate between ini and legacy dump flows to allow adding ini triggers
that are not supported in the legacy flow and to increase readabilty.

iwl_fw_dbg_ini_collect function is now called with legacy trigger id and
_iwl_fw_dbg_ini_collect is called with ini trigger id.

Also make the actual dumping function static so that any dump collection
will go through iwl_fw_dbg_collect_sync.

The layout of the RBD (receive buffer descriptor) isn't quite right,
the hardware ended up being implemented differently. Switch to the
correct RBD layout. While at it, remove the now useless extra defines.

Also, switch the CD (completion descriptor) to the right format, which
is basically just a code cleanup because the only field we really used
(rbid) is still in the same place. We may need fragmentation later if
we ever want to use it.

In restart flow, the driver requests HW restart from mac80211
and then mac80211 uses a worker to do the restart flow. In that flow a
sync dump is performed. Instead, schedule the dump worker before
requesting HW restart from mac80211. This approach simplifies the
restart flow.
Also, it is neeeded in order to differentiate between the handling of SW
and HW errors in a future commit.
