Fix tls_test unit test
Commit 11ed7aac refactored the TLS transport code and unit tests. Specifically it added the tls_test.c
file. This file includes lib/isc/tests/uv_wrap.h
but doesn't use the defined RETURN_RESET
macro. Therefore, the variables __state_uv_udp_getpeername
and __state_uv_udp_connect
are initialized but remain unused. This warning is treated as an error in the CI pipeline.
