Mikulas Patocka 058be20653 dm persistent data: fix memory allocation failure ...

commit faada2174c08662ae98b439c69efe3e79382c538 upstream.

kmalloc is unreliable when allocating more than 8 pages of memory. It may
fail when there is plenty of free memory but the memory is fragmented.
Zdenek Kabelac observed such failure in his tests.

This commit changes kmalloc to kvmalloc - kvmalloc will fall back to
vmalloc if the large allocation fails.
