Revert "hugetlb: Add hugetlb_dynamic_pool sysctl"

Browse source 
This reverts commit 54f9f80d65 ("hugetlb:
Add hugetlb_dynamic_pool sysctl")

Given the new sysctl nr_overcommit_hugepages, the boolean dynamic pool
sysctl is not needed, as its semantics can be expressed by 0 in the
overcommit sysctl (no dynamic pool) and non-0 in the overcommit sysctl
(pool enabled).

(Needed in 2.6.24 since it reverts a post-2.6.23 userspace-visible change)
