page allocator: inline buffered_rmqueue()
buffered_rmqueue() is in the fast path so inline it. Because it only has
one call site, this function can then be inlined without causing text
bloat. On an x86-based config, it made no difference as the savings were
padded out by NOP instructions. Milage varies but text will either
decrease in size or remain static.
