spi: spi-topcliff-pch: Fix potential double free in pch_spi_process_messages()
[ Upstream commit 026a1dc1af52742c5897e64a3431445371a71871 ]
pch_spi_set_tx() frees data->pkt_tx_buff on failure of kzalloc() for
data->pkt_rx_buff, but its caller, pch_spi_process_messages(), will
free data->pkt_tx_buff again. Set data->pkt_tx_buff to NULL after
kfree() to avoid double free.
