Fix evp_test HKDF failure in crosstest 3.1.2 FIPS provider with master

Fix evp_test HKDF failure in crosstest 3.1.2 FIPS provider with master

Fixes #25089
The test to check if the FIPS indicator was correct failed in 3.1.2
since EVP_PKEY_CTX_get_params() returns 0 if there is no
gettable/getter.

The code has been modified to return 1 if there is no gettable.
Manually reproduced and tested by copying the 3.1.2 FIPS provider to master.
