net: stmmac: Fix bad RX timestamp extraction
[ Upstream commit a1762456993893795030d911106a7650481db0ef ]
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.
