parisc: Fix crash when calling PDC_PAT_MEM PDT firmware function
Commit c9c2877d08d9 ("parisc: Add Page Deallocation Table (PDT) support")
introduced the pdc_pat_mem_read_pd_pdt() firmware helper function, which
crashed the system because it trashed the stack if the
pdc_pat_mem_read_pd_retinfo struct was located on the stack (and which is
in size less than the required 32 64-bit values).
Fix it by using the pdc_result struct instead when calling firmware and copy
the return values back into the result struct when finished sucessfully.
While debugging this code I noticed that the pdc_type wasn't set correctly
either, so let's fix that too.
