Pull request overview
This PR fixes a small memory leak in the LDAP transfer path by ensuring the BerElement *ber iterator state is always freed when exiting ldap_do() early due to a Curl_client_write() error (or other early-exit conditions).
Changes:
- Hoist
BerElement *berto function scope so it remains visible on all exit paths. - Centralize
bercleanup by removing repeated per-error-path frees and adding aquit:cleanup free. - Avoid double-free by setting
ber = NULLafter the normal per-entryber_free().
