smb: client: Remove unnecessary selection of CRYPTO_ECB

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

Specifically, it has been unnecessary since commit 06deeec ("cifs:
Fix smbencrypt() to stop pointing a scatterlist at the stack") in 2016.
