The PEM_read_bio_Parameters() function should not ask for a password

The PEM_read_bio_Parameters() function should not ask for a password

The PEM_read_bio_Parameters[_ex] function does not have the capability
of specifying a password callback. We should not use the fallback password
callback in this case because it will attempt to send a prompt for the
password which might not be the correct thing to do. We should just not
use a password in that case.

Fixes #21588
