startup failure in cases where multiple vhosts share the same
  "vhost-id" and private key file.  The cached-key case would
  previously cause an abrupt return from the function, which could
  prevent processing of configured keypairs for other vhosts.  There
  is no apparent reason to check for a "cache hit" against cached keys
  using *any* algorithm types; instead only check against a key with
  the matching type.
