------------------------------+--------------------------------
 When we get a v3 hsdesc where the decrypted part starts with a NUL byte,
 then decrypt_desc_layer will return 0, since the length of the output is
 0.  But "0" can also mean that there's an error in the
 decryption.

 Found with OSS-fuzz.
