wifi: iwlwifi: fw: fix DBGI dump

The DBGI dump is (unsurprisingly) of type DBGI, not SRAM.
This leads to bad register accesses because the union is
built differently, there's no allocation ID, and thus the
allocation ID ends up being 0x8000.

Note that this was already wrong for DRAM vs. SMEM since
they use different parts of the union, but the allocation
ID is at the same place, so it worked.

Fix all of this but set the allocation ID in a way that
the offset calculation ends up without any offset.
