hugetlb: remove unnecessary set_page_count in prep_compound_gigantic_page
In commit 7118fc29 ("hugetlb: address ref count racing in prep_compound_gigantic_page"), page_ref_freeze is used to atomically zero the ref count of tail pages iff they are 1. The unconditional call to set_page_count(0) was left in the code. This call is after page_ref_freeze so it is really a noop. Remove redundant and unnecessary set_page_count call.
