	The jitterentropy's Repetition Count Test (RCT) as well as the Adaptive Proportion Test (APT) are run unconditionally on any collected samples. However, their result, i.e. ->health_failure, will only get checked if fips_enabled is set, c.f. the jent_health_failure() wrapper. I would argue that a RCT or APT failure indicates that something's seriously off and that this should always be reported as an error, independently of whether FIPS mode is enabled or not: it should be up to callers whether or not and how to handle jitterentropy failures. Make jent_health_failure() to unconditionally return ->health_failure, independent of whether fips_enabled is set. Note that fips_enabled isn't accessed from the jitterentropy code anymore now. Remove the linux/fips.h include as well as the jent_fips_enabled() wrapper.
