Problem:
The new API esp_bt_mem_release() that was added freed BTDM data to heap from esp_bt_controller_mem_release().
Now with the BT memory optimization commit ee787085f9,
the BTDM data is optimized and reduced to only 32 bytes which is not sufficient amount to be added to heap.
So, using the API leads to assert saying that the region is too small.
Solution:
Modify heap_caps_add_region_with_caps to return ESP_ERR_INVALID_SIZE in case the range is too small to create a new heap.
Do not assert if return value is ESP_ERR_INVALID_SIZE
This also fixes using API esp_bt_controller_mem_release() with ESP_BT_MODE_BTDM
