smb: server: Free sensitive data in connection.c with kfree_sensitive()

Browse source

struct ksmbd_conn contains an embedded struct ntlmssp_auth with the
ciphertext[] and cryptkey[] arrays, so to avoid leaking this information
via the heap, it should be freed with kfree_sensitive().

While we're at it, also use kfree_sensitive() for freeing preauth_info
in ksmbd_conn_free() to avoid that the Preauth_HashValue[] could leak
via the heap here, too.
