RDMA/hns: Fix several memory issues in roce bonding

driver inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I6GT7F



--------------------------------------------------------------------------

Fix several memory issues in roce bonding:
1. When bond init failed, an error code is returned without device
being unregistered.
2. In the abnormal situation where hr_dev may be NULL, the printing
in hns_roce_clear_bond() will cause a kernel panic.
3. Though unlikely, there is a time gap between free(die_info) and
xa_erase(). This may lead to a potential UAF.
