[PATCH-next 1/1] lib/test_vmalloc.c: extend max value of nr_threads parameter

[Uladzislau Rezki (Sony)]

Currently a maximum value is set to 1024 workers the user can
create during the test. It might be that for some big systems
it is not enough. Since it is a test thing we can give testers
more flexibility.

Increase that number till USHRT_MAX that corresponds to 65535.
