* @brief Reverse-map a Host pseudo address to the real peer identity.
*
* When CONFIG_BT_BLE_PERIPH_PSEUDO_ADDR_BOND is enabled, the
* remote_bda reported to the application for a dual local
* identity link is a Host-internal pseudo address (one peer
* phone connected through two local identities shows up as two
* different pseudo addresses). This helper returns the actual
* over-the-air peer identity for UI / diagnostics.
*
* **Must be called while the link is connected.** The mapping
* lives in a Host-side connection table that is cleared on
* disconnect. If there is no active link for `pseudo`, the call
* returns `ESP_FAIL` and `real_peer` is not modified.
*
* For offline bond information, use
* `esp_ble_get_bond_device_list()` and read
* `bond_key.pid_key.static_addr` for the real peer identity.
*
* @param[in] pseudo - the pseudo address as seen in remote_bda
* @param[out] real_peer - filled with the real peer identity on success
*
* @return - ESP_OK : success (link connected and pseudo known)
* - ESP_FAIL : Bluedroid not enabled, or pseudo not found /
* not connected
