crypto: drbg - Fix the fips_enabled priority boost
When fips_enabled=1, it seems to have been intended for one of the
algorithms defined in crypto/drbg.c to be the highest priority "stdrng"
algorithm, so that it is what is used by "stdrng" users.
However, the code only boosts the priority to 400, which is less than
the priority 500 used in drivers/crypto/caam/caamprng.c. Thus, the CAAM
RNG could be used instead.
Fix this by boosting the priority by 2000 instead of 200.
