drm/tests: shmem: Add clean-up action to unpin pages

Browse source

[ Upstream commit b47b9ecef3 ]

Automatically unpin pages on cleanup. The test currently fails with
the error

[   58.246263] drm-kunit-mock-device drm_gem_shmem_test_get_sg_table.drm-kunit-mock-device: [drm] drm_WARN_ON(refcount_read(&shmem->pages_pin_count))

while cleaning up the GEM object. The pin count has to be zero at this
point.
