RDMA/hns: Fix memory leak of bonding resources

In a corner case of concurrent driver removal and driver reset,
bonding resource is first released in hns_roce_hw_v2_exit() during
driver removal, and then is allocated again in hns_roce_register_device()
during driver reset. This leads to memory leak because the release
timing has already passed. This may also lead to a kernel panic
as below because of the leaked notifier callback:

Call trace:
0xffffa20fccc04978 (P)
raw_notifier_call_chain+0x20/0x38
call_netdevice_notifiers_info+0x60/0xb8
netdev_lower_state_changed+0x4c/0xb8

As Sashiko suggested, the teardown order of bonding resources should
be inverted to make sure the resources are released when the driver
is removed.
