    ramips: Fix cmpilation
    
    Fixes this compile problem:
    ```
    drivers/net/ethernet/ralink/esw_rt3050.c: In function 'rt3050_esw_init':
    drivers/net/ethernet/ralink/esw_rt3050.c:1467:12: error: 'pdev' is used uninitialized [-Werror=uninitialized]
     1467 |         if (!pdev)
          |            ^
    drivers/net/ethernet/ralink/esw_rt3050.c:1461:33: note: 'pdev' was declared here
     1461 |         struct platform_device *pdev;
          |                                 ^~~~
    cc1: all warnings being treated as errors
    ```
