Richard Levitte ecfbe2f046 DSA: Make DSA_bits() and DSA_size() check that there are key parameters
Without these check, a DSA structure without key parameters will cause
these functions to crash.  This is also the case in pre-3.0 OpenSSL,
but since we now extract these data early, to cache them in the
EVP_PKEY structure, the same crash happens earlier and much more
internally.

The added checks are of the same kind as DSA_security_bits() already
does.

Fixes #13610
