Subject: [PATCH] Avoid returning enum in boolean context
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Without this fix, when compiling with `ENABLE_CRYPTO_REFRESH`, we see:

```
…/src/lib/enc_material.cpp: In member function ‘virtual bool pgp::X25519EncMaterial::parse(pgp_packet_body_t&)’:
…/src/lib/enc_material.cpp:154:20: warning: enum constant in boolean context [-Wint-in-bool-context]

      |                    ^~~~~~~~~~~~~~~~~~~~
