    wifi-scripts: iwinfo: add null checks for rx/tx bitrate
    
    On some devices, the rx/tx bitrate may not always be available
    right away, or at all when in mesh mode at plink is blocked causing
    the following:
    
    ```
    Reference error: left-hand side expression is null
    In assoclist(), file /usr/share/ucode/iwinfo.uc, line 321, byte 46:

      called from anonymous function (/usr/bin/iwinfo:108:25)
    
     `                bitrate_raw: station.sta_info.tx_bitrate.bitrate,`

    This was seen on Linksys MX5300 in mesh mode (QCA9984).
