From: Baolin Wang <baolin.wang@xxxxxxxxxxxxxxxxx>
Subject: hugetlb: remove redundant VM_BUG_ON() in add_reservation_in_range()
When calling hugetlb_resv_map_add(), we've guaranteed that the parameter
'to' is always larger than 'from', so it never returns a negative value
from hugetlb_resv_map_add(). Thus remove the redundant VM_BUG_ON().
