page allocator: inline buffered_rmqueue()

Browse Source 
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.
