bitmap_zero() is called after bitmap_alloc() in perf code. But
bitmap_alloc() internally uses calloc() which guarantees that allocated
area is zeroed. So following bitmap_zero is unneeded. Drop it.
This happened because of confusing name for bitmap allocator. It
should has name bitmap_zalloc instead of bitmap_alloc.
This series:
https://lkml.org/lkml/2018/6/18/841
introduces a new API for bitmap allocations in kernel, and functions
there are named correctly. Following patch propogates the API to tools,
and fixes naming issue.

Adding mem2node object automated test.
The test prepares few artificial nodes - memory maps and verifies the
mem2node object returns proper node values to given addresses.
