Taehee Yoo 0299f24a97 hsr: add hsr root debugfs directory
commit c6c4ccd7f96993e106dfea7ef18127f972f2db5e upstream.

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
