net: stmmac: Fix bad RX timestamp extraction

Browse source

[ Upstream commit a176245699 ]

As noted in dwmac4_wrback_get_rx_timestamp_status the timestamp is found
in the context descriptor following the current descriptor. However the
current code looks for the context descriptor in the current
descriptor, which will always fail.
