Sinan Kaya 8ff3b0cd63 Support LOOP_CONFIGURE ioctl to improve speed ...

More data about the new IOCTL is here:
https://lwn.net/Articles/818870/

We see 200-500ms boot speed improvement on our platform.

Prefer to define IOCTL when kernel is older version. Also eliminate
duplication since as a result of introduced ifdef.
