The drm_buddy_test's alloc_contiguous test used a u64 for the page size, which was then updated to be an 'unsigned long' to avoid 64-bit multiplication division helpers.
However, the variable is logged by some KUNIT_ASSERT_EQ_MSG() using the '%d' or '%llu' format specifiers, the former of which is always wrong, and the latter is no longer correct now that ps is no longer a u64. Fix these to all use '%lu'.
Also, drm_mm_test calls KUNIT_FAIL() with an empty string as the message. gcc warns if a printf format string is empty (apparently), so give these some more detailed error messages, which should be more useful anyway.

- At this point we should have enough contiguous space for 2 blocks,
- however they are never buddies (since we freed middle and right) so
