Call PyBuffer_Release() if PyObject_GC_New() fails.

Fix also bytes_join(): only call Py_DECREF(item) after formatting the error message which uses item.

Tests / Windows / Build and test (x64, tail-call) (pull_request): Failing after 10m

It's a test_logging test which fails randomly: I reported the bug to issue gh-84649.

FAIL: test_rollover_at_midnight (test.test_logging.TimedRotatingFileHandlerTest.test_rollover_at_midnight)
