  Log Message:
  -----------
  test/bad_dtls_test.c: Add checks for the EVP_MD_CTX_get_size()

Add the check for the EVP_MD_CTX_get_size() to avoid integer overflow when it is implicitly casted from int to size_t in evp_pkey_ctx_store_cached_data().
The call path is do_PRF() -> EVP_PKEY_CTX_add1_tls1_prf_seed() -> evp_pkey_ctx_set1_octet_string() -> EVP_PKEY_CTX_ctrl() -> evp_pkey_ctx_store_cached_data().

Fixes: 16938284cf ("Add basic test for Cisco DTLS1_BAD_VER and record replay handling")
