[PULL 1/4] block/curl: free s->password in cleanup paths

[Kevin Wolf <kwolf@redhat.com>]

From: GuoHan Zhao <zhaoguohan@kylinos.cn>

When password-secret is used, curl_open() resolves it with
qcrypto_secret_lookup_as_utf8() and stores the returned buffer in
s->password.

Unlike s->proxypassword, s->password is not freed either in the open
failure path or in curl_close(), so the resolved secret leaks once it
has been allocated.

Free s->password in both cleanup paths.

Fixes: 1bff96064290 ('curl: add support for HTTP authentication parameters')
