Guido Casati e179a6df8f fix (UE RRC): queue MAC reset before RLC teardown on RRCSetup fallback ...

When the gNB answers RRCReestablishmentRequest with RRCSetup (TS 38.331
clause 5.3.3.4 fallback), the UE must release all bearers except SRB0 before
applying the new masterCellGroup. CONFIG_RESET was queued after RLC release,
so the MAC slot thread kept polling LCID 1 from a stale lc_ordered_list while
the RLC entity was already NULL.

Queue NR_MAC_RRC_CONFIG_RESET (RRC_SETUP_REESTAB_RESUME) first, then release
PDCP, RLC, and SDAP. On the MAC thread, clear lc_ordered_list except SRB0
before release_mac_configuration() so the UL scheduler stops looping released
logical channels until CONFIG_CG re-adds SRB1.

Changes:
- rrc_UE.c: move CONFIG_RESET to the start of nr_rrc_rrcsetup_fallback()
- config_ue.c: drop non-SRB0 lc_ordered_list entries on RRC_SETUP_REESTAB_RESUME

Closes: #128
