page allocator: inline __rmqueue_fallback()
__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.
