rhashtable: Make selftest modular Allow the selftest on the resizable hash table to be built modular, just like all other tests that do not depend on DEBUG_KERNEL.

rhashtable: don't allocate ht structure on stack in test_rht_init With object runtime debugging enabled, the rhashtable test suite will rightfully throw a warning "ODEBUG: object is on stack, but not annotated" from rhashtable_init(). This is because run_work is (correctly) being initialized via INIT_WORK(), and not annotated by INIT_WORK_ONSTACK(). Meaning, rhashtable_init() is okay as is, we just need to move ht e.g., into global scope. It never triggered anything, since test_rhashtable is rather a controlled environment and effectively runs to completion, so that stack memory is not vanishing underneath us, we shouldn't confuse any testers with it though.

rhashtable: remove indirection for grow/shrink decision functions Currently, all real users of rhashtable default their grow and shrink decision functions to rht_grow_above_75() and rht_shrink_below_30(), so that there's currently no need to have this explicitly selectable. It can/should be generic and private inside rhashtable until a real use case pops up. Since we can make this private, we'll save us this additional indirection layer and can improve insertion/deletion time as well.

rhashtable: allow to unload test module There's no good reason why to disallow unloading of the rhashtable test case module. Commit 9d6dbe1bbaf8 moved the code from a boot test into a stand-alone module, but only converted the subsys_initcall() handler into a module_init() function without a related exit handler, and thus preventing the test module from unloading.
