KEYS: trusted_tpm1: Compare HMAC values in constant time
To prevent timing attacks, HMAC value comparison needs to be constant
time. Replace the memcmp() with the correct function, crypto_memneq().
[For the Fixes commit I used the commit that introduced the memcmp().
It predates the introduction of crypto_memneq(), but it was still a bug
at the time even though a helper function didn't exist yet.]
Fixes: d00a1c72f7f4 ("keys: add new trusted key-type")
