fix (sdap): copy entity_role on reflective QoS mapping

Browse Source 
After new per-DRB SDAP roles changes, UE downlink reflective mapping
(TS 37.324 §5.3.2) still stored only drb_id on the new QFI row.
entity_role stayed NO_SDAP_HEADER, so later uplink TX and §5.3.1
end-marker logic read the wrong header config from that row.

When storing the reflective UL rule, copy the receiving DRB entity_role
(from nr_sdap_drb_lookup) together with drb_id, matching qfi2drb_map_add.

Changes:
- nr_sdap_rx_entity(): set qfi2drb_table[qfi].entity_role on RDI store

Refs:
- TS 37.324 §5.3.1, §5.3.2
- TS 38.331 SDAP-Config (sdap-HeaderUL / sdap-HeaderDL)
