[FLINK-9766][network][tests] fix cleanup in RemoteInputChannelTest
## What is the purpose of the change
If an assertion in the tests of `RemoteInputChannelTest` fails and as a
result the cleanup fails, in most tests the original assertion was swallowed
making it hard to debug.
Furthermore, `#testConcurrentRecycleAndRelease2()` does even not clean up
at all
if successful.
## Brief change log
- add a helper method to unify (correct) cleanup so that if an exception is
thrown in the `finally` block, it will be added as a suppressed exception
## Verifying this change
This change is a trivial rework / code cleanup without any test coverage.
