staging: pi433: enforce tx_cfg to be set before any message can be sent
this driver relies on exposing a char device to userspace to tx
messages. Every message can be sent using different trasmitter settings
such so the tx_cfg must be written before sending any messages.
Failing to do so will cause the message to fail silently depending on
printk/dynamic_debug settings which makes it hard to troubleshoot.
This patch add a control variable that will get initialized once tx_cfg
is set for the fd used when interacting with the char device.
