block/034: Test memory is released by null-blk driver with memory_backed=1

This tests memory leak, by loading/unloading nullblk driver.
Steps:
1. Load nullblk driver with memory_backed=1
2. "dd" of 50M
3. Unload null-blk driver
We do it for 5 iterations to avoid any noise.

Commit 8cfb98196cceec35416041c6b91212d2b99392e4 fixes issue in kernel
