commit 4eca3ec728f328a1b05553814e58ca9aa1cb4e78

Clarify the usage of EVP_PKEY_get_raw_[private|public]_key()
EVP_PKEY_get_raw_private_key() and EVP_PKEY_get_raw_public_key() expect
the size of the key buffer to be populated in the |*len| parameter on
entry - but the docs made no mention of this.
Fixes #11245
