[ Upstream commit 2bf4b33f83dfe521c4c7c407b6b150aeec04d69c ]
If the set_txreq_header_agh() function returns an error, the exit path is chosen.
In this path, the code fails to set the return value. This will cause the caller to not realize an error has occurred.
Set the return value correctly in the error path.
