wlwifi AX201: WARN_ON in iwl_mvm_mld_mac_ctxt_cmd_common repeated UMAC FW crashes on 6.16-rc2

Hi Miri,
Hi all,

with v6.16-rc2 I consistently hit a Wi-Fi firmware crash on a
Lenovo ThinkPad X1 Carbon Gen 9.

Hardware / FW
-------------
 * NIC  : Intel Wi-Fi 6 AX201 160 MHz (PCI ID a0f0:0070, rev 0x351)
 * FW   : 77.864baa2e.0 QuZ-a0-hr-b0-77.ucode (auto-loaded)
 * BIOS : N32ET96W (1.72)
 * Platform: 20XWCTO1WW

Kernel: 6.16.0-rc2 #440 PREEMPT(lazy)

Symptoms
--------
Immediately after NetworkManager (or plain `ip link set wlp0s20f3 up`)
the driver warns:

    WARNING at drivers/net/wireless/intel/iwlwifi/mvm/mld-mac.c:37
    iwl_mvm_mld_mac_ctxt_cmd_common+0x175/0x1d0

The firmware then aborts:

    FW error in SYNC CMD MAC_CONFIG_CMD
    NMI_INTERRUPT_UMAC_FATAL
    ADVANCED_SYSASSERT 0x20103126
    Microcode SW error detected. Restarting 0x0.

The cycle repeats every few seconds; the interface never becomes usable.
Full dmesg attached.
