net: hns3: refactor dump tm map of debugfs
Currently, the debugfs command for tm map is implemented by
"echo xxxx > cmd", and record the information in dmesg. It's
unnecessary and heavy. To improve it, create a single file
"tm_map" for it, and query it by command "cat tm_map",
return the result to userspace, rather than record in dmesg.
As user can't specify queue id in cat command, driver will return info
of all queue id.
The display style is below:
$ cat tm_map
queue_id qset_id pri_id tc_id
0000 0000 00 00
