lib/test_vmalloc.c: use late_initcall() if built-in for init ordering
When the vmalloc test code is compiled as a built-in, use late_initcall()
instead of module_init() to defer a vmalloc test execution until most
subsystems are up and running.
It avoids interfering with components that may not yet be initialized at
module_init() time. For example, there was a recent report of memory
profiling infrastructure not being ready early enough leading to kernel
crash.
By using late_initcall() in the built-in case, we ensure the tests are run
at a safer point during a boot sequence.
