BUILD: stream-int: avoid a build warning when DEBUG is empty
When no DEBUG_STRICT is enabled, we get this build warning:
src/stream_interface.c: In function 'stream_int_chk_snd_conn':
src/stream_interface.c:1198:28: warning: unused variable 'conn' [-Wunused-variable]
1198 | struct connection *conn = cs_conn(cs);
| ^~~~
This was the result of the simplification of the code in commit
d1480cc8a ("BUG/MEDIUM: stream-int: do not rely on the connection error
once established") which removed the last user of this variable outside
of a BUG_ON().
If the patch above is backported, this one should be backported as well.
