[PATCH] crypto: Allow ecb(cipher_null) in FIPS mode

[Milan Broz]

The cipher_null is not a real cipher, FIPS mode should not restrict its use.

It is used for several tests (for example in cryptsetup testsuite) and also
temporarily for reencryption of not yet encrypted device in 
cryptsetup-reencrypt tool.

Problem is easily reproducible with
  cryptsetup benchmark -c null
