====================
net: dsa: remove unnecessary i2c_set_clientdata()

This patchset https://lore.kernel.org/all/20220921140524.3831101-8-yangyingliang@huawei.com/T/
removed all set_drvdata(NULL) in driver remove function.

i2c_set_clientdata() is another wrapper of set drvdata function, to follow
the same convention, remove i2c_set_clientdata() called in driver remove
function in drivers/net/dsa/.
