lib/env_ocf: place allocator variable on hugepages

Browse Source 
When using `__lsan_do_recoverable_leak_check` (e.g when fuzzing),
to check for leaks during runtime. Leak sanitizer can not follow
reference of memory that is allocated on heap (e.g. calloc)
and then stored on hugepage causing lsan to incorrectly report
direct leak.

Fixes #2967
