echainiv is the only algorithm or template in the crypto API that is
enabled by default. But there doesn't seem to be a good reason for it.
And it pulls in a lot of stuff as dependencies, like AEAD support and a
"NIST SP800-90A DRBG" including HMAC-SHA256.
The commit which made it default 'm', commit
3491244c6298 ("crypto:
echainiv - Set Kconfig default to m"), mentioned that it's needed for
IPsec. However, later commit
32b6170ca59c ("ipv4+ipv6: Make INET*_ESP
select CRYPTO_ECHAINIV") made the IPsec kconfig options select it.
So, remove the 'default m'.
