net: vertexcom: mse102x: Fix RX error handling

Browse source

[ Upstream commit ee512922dd ]

In case the CMD_RTS got corrupted by interferences, the MSE102x
doesn't allow a retransmission of the command. Instead the Ethernet
frame must be shifted out of the SPI FIFO. Since the actual length is
unknown, assume the maximum possible value.
