net: ethernet: mediatek: remove return value check of `mtk_wed_hw_add_debugfs` 

Smatch complains that:
mtk_wed_hw_add_debugfs() warn: 'dir' is an error pointer or valid

Debugfs checks are generally not supposed to be checked
for errors and it is not necessary here.

fix it by just deleting the dead code.
