Compilation on CentOS 7 with gcc version 4.8.5 fails with
the following errors:
```
...
error: 'src_struct_id' may be used uninitialized in this
function [-Werror=maybe-uninitialized]
...
error: 'dst_struct_id' may be used uninitialized in this
function [-Werror=maybe-uninitialized]
...
```

This patch fixes the build errors by initializing both variables.

Bugzilla ID: 683
Fixes: 783768136f29 ("pipeline: auto-detect endianness of action arguments")

This patch was depending on others so CI didn't run.
I've requested a partial CI run when dependencies resolved and it passed.
That's what happens when I merge a patch without a re-run of the full CI.
We really need to be able to re-run CI easily,
plus managing the dependencies in the CI.
