memory: renesas-rpc-if: Fix missing setting address

In the RPC manual mode, if the data direction is not set
(such as the flash erase command), the address misses the
setting.

This patch never received review comments.
As of commit fff53a551db50f5e ("memory: renesas-rpc-if: Correct QSPI
data transfer in Manual mode") in v5.16-rc1, RPCIF_SMADR is written
before the switch() statement, hence this patch can be ignored.

Thanks Geert. The patch was not sent to proper folks and mailing lists
(only linux-renesas-soc@vger.kernel.org seams reasonable) so there is
little way it would be ever reviewed.

Zhengxun,
Please use scripts/get_maintainer.pl to get the list of people and lists
to CC/address.


Best regards,
