Subject: ksmbd: Remove unnecessary selection of CRYPTO_ECB
X-Git-Tag: v7.1-rc1~136^2~9

ksmbd: Remove unnecessary selection of CRYPTO_ECB

Since the SMB server never uses any ecb(...) algorithm from the
crypto_skcipher API, selecting CRYPTO_ECB is unnecessary.

Remove it along with the unused CRYPTO_BLK_* constants.
