crypto: FIPS - allow tests to be disabled in FIPS mode
In FIPS mode, additional restrictions may apply. If these restrictions are violated, the kernel will panic(). This patch allows test vectors for symmetric ciphers to be marked as to be skipped in FIPS mode. Together with the patch, the XTS test vectors where the AES key is identical to the tweak key is disabled in FIPS mode. This test vector violates the FIPS requirement that both keys must be different.
