Subject: [PATCH] Fix potential use of uninitialized pgp struct

We only call initPgpData() after base64 encoding the pubkey so if the
latter fails, the kd struct will be left uninitialized and subsequently
read from after skipping to the exit label.  Fix by initializing it.

Found by Coverity.

Fixes: RHEL-22605
