Commit c4741b2305979 ("crypto: run initcalls for generic implementations
earlier") converted tcrypt.ko's module_init() to subsys_initcall(), but
this was unintentional: tcrypt.ko currently cannot be built into the core
kernel, and so the subsys_initcall() gets converted into module_init()
under the hood. Given that tcrypt.ko does not implement a generic version
of a crypto algorithm that has to be available early during boot, there
is no point in running the tcrypt init code earlier than implied by
module_init().

However, for crypto development purposes, we will lift the restriction
that tcrypt.ko must be built as a module, and when builtin, it makes sense
for tcrypt.ko (which does its work inside the module init function) to run
as late as possible. So let's switch to late_initcall() instead.
