When the VF fail to set the default MAC address,
"hw->mac.mac_addr" should not be updated.

From: Chengwen Feng <fengchengwen@huawei.com>
The driver-related TM (traffic management) info is implemented through
the linked list. The following threads are involved in the read and
write of the TM info:
1. main thread: invokes the rte_tm_xxx() API family to modify or read.
2. interrupt thread: will read TM info in reset recover process.
3. telemetry/proc-info thread: invoke rte_eth_dev_priv_dump() API to
read TM info.
Currently, thread safety protection of TM info is implemented only in
the following operations:
1. some of the rte_tm_xxx() API's implementation.
2. reset recover process.
Thread safety risks may exist in other scenarios, so fix by:
1. make sure all the rte_tm_xxx() API's implementations protected by
hw.lock.
2. make sure rte_eth_dev_priv_dump() API's implementation protected
by hw.lock.

From: Chengwen Feng <fengchengwen@huawei.com>
Currently the dumped TM info is un-align, which are:
- TM config info:
-- nb_leaf_nodes_max=64 nb_nodes_max=73
-- nb_shaper_profile=2 nb_tc_node=1 nb_queue_node=1
-- committed=0
shaper_profile:
id=800 reference_count=1 peak_rate=4000000Bps
id=801 reference_count=1 peak_rate=12000000Bps
port_node:
...
This patch fix it, the new formatting:
- TM config info:
-- nb_leaf_nodes_max=256 nb_nodes_max=265
-- nb_shaper_profile=2 nb_tc_node=1 nb_queue_node=1
-- committed=1
-- shaper_profile:
id=800 reference_count=0 peak_rate=4000000Bps
id=801 reference_count=0 peak_rate=12000000Bps
-- port_node:
