drm/buddy: Fix the warn on's during force merge

Move the fallback and block incompatible checks
above, so that we dont unnecessarily split the blocks
and leaving the unmerged. This resolves the unnecessary
warn on's thrown during force_merge call.

v2:(Matthew)
  - Move the fallback and block incompatible checks above
    the contains check.
