_pool_init_fixed uses mmap to initialize a fixed-size and preallocated
pool, whose size is the sum of vector_size and free_index_size with
alignment to the CLIB_CACHE_LINE_BYTES and page size. In this way
vector_size equals to pool_header_t + vec_header_t + elt_size * max_elts
so moving to the end of the pool space should be pool_header_t pointer +
vector_size, instead of vec_header_t pointer + vector_size.
Simple code to reproduce this error:
u64 *pool;
pool_init_fixed(pool, 2042);
Improve unit test to cover this case
