hsr: add hsr root debugfs directory
In current hsr code, when hsr interface is created, it creates debugfs
directory /sys/kernel/debug/<interface name>.
If there is same directory or file name in there, it fails.
In order to reduce possibility of failure of creation of debugfs,
this patch adds root directory.
Test commands:
ip link add dummy0 type dummy
ip link add dummy1 type dummy
ip link add hsr0 type hsr slave1 dummy0 slave2 dummy1
Before this patch:
/sys/kernel/debug/hsr0/node_table
After this patch:
/sys/kernel/debug/hsr/hsr0/node_table
