drm/i915/selftests: Rework context handling in hugepages selftests

Browse source

In the next commit, we don't evict when refcount = 0, so we need to
call drain freed objects, because we want to pin new bo's in the same
place, causing a test failure.

Furthermore, since each subtest is separated, it's a lot better to use
i915_live_selftests, so each subtest starts with a clean slate, and a
clean address space.

v2(Reported-by: kernel test robot <lkp@intel.com>):
  - Make hugepage_ctx static.
