In the Linux kernel, the following vulnerability has been resolved: RDMA/hns: Fix double destruction of rsv_qp rsv_qp may be double destroyed in error flow, first in free_mr_init(),
and then in hns_roce_exit(). Fix it by moving the free_mr_init() call
into hns_roce_v2_init(). list_del corruption, ffff589732eb9b50->next is LIST_POISON1 (dead000000000100)
