====================
net: ethernet: mtk_eth_wed: fixe some leaks

I found some leaks in mtk_eth_soc.c/mtk_wed.c.

 patch#1 - I found mtk_wed_exit() is never called, I think mtk_wed_exit() need
           be called in error path or module remove function to free the memory
           allocated in mtk_wed_add_hw().

 patch#2 - The device is not put in error path in mtk_wed_add_hw().

 patch#3 - The device_node pointer returned by of_parse_phandle() with refcount
           incremented, it should be decreased when it done.

This patchset was just compiled tested because I don't have any HW on
which to do the actual tests.
