Subject: [PATCH 3/4 net] qca_spi: Fix ethtool -G iface tx behavior

After calling ethtool -g it was not possible to adjust the TX ring size
again. The reason for this is that the readonly setting rx_pending get
initialized and after that the range check in qcaspi_set_ringparam()
fails regardless of the provided parameter. Since there is no adjustable
RX ring at all, drop it from qcaspi_get_ringparam().

Fixes: 291ab06ecf67 ("net: qualcomm: new Ethernet over SPI driver for QCA7000")
