[PATCH v2] net: ethernet: ag71xx: Remove dead code

[Muhammad Usama Anjum]

The err variable isn't being used anywhere other than getting
initialized to 0 and then it is being checked in if condition. The
condition can never be true. Remove the err and deadcode.

Move the rx_dropped counter above when skb isn't found.
