Description: Fixes #146245 Summary Two leak bugs in socketmodule.c when PySys_Audit raises: 1. getaddrinfo (line 6985) return NULL skipped cleanup of idna and pstr refs. Changed to goto err which properly calls Py_XDECREF on both. 2. sock_sendto (line 4811) return NULL skipped PyBuffer_Release(&pbuf). Added the release before the return, matching the pattern used in adjacent error paths. Issue: gh-146245
