[PATCH for-next 2/6] RDMA/hns: Remove the unused hns_roce_bitmap_free_range function

[Weihang Li <liweihang@huawei.com>]

From: Yangyang Li <liyangyang20@huawei.com>

hns_roce_bitmap_free_range() is only called inside hns_roce_bitmap_free(),
and the input parameter "cnt" is set to a constant 1. In addition, the
driver does not use alloc_range scenarios, so free_range does not need to
exist.
