Avoid "unused variable" warning on non-USE_SSL_ENGINE platforms.

Browse Source 
If we are building with openssl but USE_SSL_ENGINE didn't get set,
initialize_SSL's variable "pkey" is declared but used nowhere.
Apparently this combination hasn't been exercised in the buildfarm
before now, because I've not seen this warning before, even though
the code has been like this a long time.  Move the declaration
to silence the warning (and remove its useless initialization).

Per buildfarm member sawshark.  Back-patch to all supported branches.
