net: hns3: refactor dump qs shaper of debugfs
Currently, user gets qset shaper parameters by implementing debugfs
command "echo dump qs shaper > cmd", this command will dump info in
dmesg. It's unnecessary and heavy.
As there is "tm_qset" file in tm directory for dump qset info, to
optimize these command, merge qset shaper parameters to tm_qset
file and use cat command to get them.
The display style is below:
$ cat tm_qset
ID MAP_PRI LINK_VLD MODE DWRR IR_B IR_U IR_S BS_B BS_S FLAG
0000 0 1 dwrr 100 150 7 0 5 20 0
0001 0 0 sp 0 150 7 0 5 20 0
