Also set cur_nps early so the record carries the target nps even when the conversion returns early.

drm/amd/ras: add get_die_id for uniras umc v12 2026-08-06T16:46:18+00:00 Tao Zhou tao.zhou1@amd.com 2026-07-27T07:39:13+00:00 220b9c3ad727b9a723360e950b3c67990210bb51 For legacy ras eeprom format(only existed on nps1 system), die id (node instance) is not stored, we get it from mca address and physical address (pa) here, and now we can calculate pa in any nps mode for legacy ras eeprom data as well. It only applies to num_umc == 16 / UMC_VRAM_TYPE_HBM parts. Also factor out __ras_umc_eeprom_rec2nps_addr() so the die id can be passed in.
