because nsh module isn't selected by openvswitch
v7->v8

- Change pop_nsh to adapt to nsh kernel module
- Fix many issues per comments from Jiri Benc

which will be final format and won't change
per its author's confirmation.
- Fix comments for v3.
v2->v3

OVS master and 2.8 branch has merged NSH userspace
patch series, this patch is to enable NSH support

NSH in compat mode by porting this.
