openssl req: don't try to report bits

With the introduction of -pkeyopt, the number of bits may change
without |newkey| being updated.  Unfortunately, there is no API to
retrieve the information from a EVP_PKEY_CTX either, so chances are
that we report incorrect information.  For the moment, it's better not
to try to report the number of bits at all.

Fixes #7086
