[PATCH 13/22] Inline __rmqueue_fallback()

[Mel Gorman]

__rmqueue_fallback() is in the slow path but has only one call site. Because
there is only 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.
