  1. Fix error propagatation in BN_check_prime() 

    BN_check_prime() is supposed to return 0 for a composite number and -1
on error. Properly translate the return value of the internal function
ossl_bn_miller_rabin_is_prime(), where 0 means an error.

The confusion prevented BN_GENCB callbacks from aborting the primality
test or key generation routines utilizing this.
