memory: renesas-rpc-if: Return correct value to the caller of rpcif_manual_xfer()
In the error path of rpcif_manual_xfer() the value of ret is overwritten by value returned by reset_control_reset() function and thus returning incorrect value to the caller. This patch makes sure the correct value is returned to the caller of rpcif_manual_xfer() by dropping the overwrite of ret in error path. Also now we ignore the value returned by reset_control_reset() in the error path and instead print a error message when it fails.
