[PATCH] net: macb: remove unnecessary code

[Claudiu.Beznea]

From: Claudiu Beznea <claudiu.beznea@xxxxxxxxxxxxx>

Commit 653e92a9175e ("net: macb: add support for padding and fcs
computation") introduced a bug fixed by commit 899ecaedd155 ("net:
ethernet: cadence: fix socket buffer corruption problem"). Code removed
in this patch is not reachable at all so remove it.

Fixes: 653e92a9175e ("net: macb: add support for padding and fcs computation")
