wifi: ath12k: do not advertise MLD peer ID for firmware-allocate devices

ath12k_peer_assoc_h_mlo() unconditionally sets ml->peer_id_valid and copies
ahsta->ml_peer_id (with the ATH12K_PEER_ML_ID_VALID bookkeeping bit masked
off) into the WMI_PEER_ASSOC_CMDID ML params, which causes
ath12k_wmi_send_peer_assoc_cmd() to set ATH12K_WMI_FLAG_MLO_PEER_ID_VALID.
This needs to be gated on chips where the firmware allocates the MLD peer
ID:

  - WCN7850/QCC2072 firmware always picks the ID itself and does not honor
    a host-supplied one, so the value would be silently ignored anyway;
  - QCC2072 firmware additionally crashes during MLO disconnect when
    ATH12K_WMI_FLAG_MLO_PEER_ID_VALID was set in the preceding peer assoc,
    so the bit must not be sent at all.

Branch on ah->host_alloc_ml_id:

  - When true (QCN9274 etc.), behavior is unchanged: peer_id_valid is set
    and the raw ahsta->ml_peer_id (without the VALID bit) is sent down.
  - When false (WCN7850, QCC2072), peer_id_valid stays unset and
    ml_peer_id is sent as 0. The firmware ignores both fields and reports
    the ID it allocated through HTT_T2H_MSG_TYPE_MLO_RX_PEER_MAP.

The early-return on ahsta->ml_peer_id == ATH12K_MLO_PEER_ID_INVALID only
applies on the host-alloc path, since on the firmware-alloc path the value
is ATH12K_MLO_PEER_ID_PENDING here, not INVALID.

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.1.c5-00302-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.115823.3
