crypto: lib/chacha - restore ability to remove modules

Though the module_exit functions are now no-ops, they should still be
defined, since otherwise the modules become unremovable.

Fixes: 08820553f33a ("crypto: arm/chacha - remove the redundant skcipher algorithms")
Fixes: 8c28abede16c ("crypto: arm64/chacha - remove the skcipher algorithms")
Fixes: f7915484c020 ("crypto: powerpc/chacha - remove the skcipher algorithms")
Fixes: ceba0eda8313 ("crypto: riscv/chacha - implement library instead of skcipher")
Fixes: 632ab0978f08 ("crypto: x86/chacha - remove the skcipher algorithms")
