pfn_pdx_hole_setup is meant to skip the first MAX_ORDER bits, but actually it only skips the first MAX_ORDER-1 bits. The issue was probably introduced by bdb5439c3f ("x86_64: Ensure frame-table compression leaves MAX_ORDER aligned"), when changing to loop to start from MAX_ORDER-1 an adjustment by 1 was needed in the call to find_next_bit() but not done.Fix the issue by passing j+1 and i+1 to find_next_zero_bit and find_next_bit. Also add a check for i >= BITS_PER_LONG because find_{,next_}zero_bit() are free to assume that their last argument is less than their middle one.
