Hangbin Liu deef40c47e crypto: x86/curve25519 - fix cpu feature checking logic in mod_exit 
[ Upstream commit 1b82435d17774f3eaab35dce239d354548aa9da2 ]

In curve25519_mod_init() the curve25519_alg will be registered only when
(X86_FEATURE_BMI2 && X86_FEATURE_ADX). But in curve25519_mod_exit()
it still checks (X86_FEATURE_BMI2 || X86_FEATURE_ADX) when do crypto
unregister. This will trigger a BUG_ON in crypto_unregister_alg() as
alg->cra_refcnt is 0 if the cpu only supports one of X86_FEATURE_BMI2
and X86_FEATURE_ADX.

Fixes: 07b586fe06 ("crypto: x86/curve25519 - replace with formally verified implementation")
