KUDU-3063: Set a ratio as multiplication factor for memkind_malloc_usable_size
Due to memkind fragmentation issues, evictions will not happen in
NVM lru cache. The charge of items in nvm cache calculated by
memkind_malloc_usable_size will never exceed the capacity.
The fragmentation can be estimated by
https://github.com/memkind/memkind/blob/master/test/fragmentation_benchmark_pmem.cpp
