lantiq: net: fix duplicated skb in rx descriptor ring

Browse source

[ Upstream commit 7ea6cd16f1 ]

The previous commit didn't fix the bug properly. By mistake, it replaces
the pointer of the next skb in the descriptor ring instead of the current
one. As a result, the two descriptors are assigned the same SKB. The error
is seen during the iperf test when skb_put tries to insert a second packet
and exceeds the available buffer.
