Subject: [PATCH net-next 7/7] net: pcs: xpcs: remove return statements in void
 function

While using "return" when calling a void returning function inside a
function that returns void doesn't cause a compiler warning, it looks
weird. Convert the bunch of if() statements to a switch() and remove
these return statements.
