Subject: [PATCH] mbedtls: fix `-Wunused-variable` when building with
 `LIBSSH2_NO_RSA`

Fixing:
```
src/mbedtls.c:721:24: error: unused variable 'method_buf_len' [-Wunused-variable]
  721 |     size_t keylen = 0, method_buf_len = 0;
      |                        ^~~~~~~~~~~~~~
src/mbedtls.c:717:56: error: unused parameter 'pkey' [-Wunused-parameter]
  717 |                              const mbedtls_pk_context *pkey)
      |                                                        ^
```

Closes #2623
