Good catch!

Strangely enough, I am not able to reproduce this bug - I posted logs
to the GitHub issue.
Fix indeed makes sense. Indeed, according to docs, UnmapViewOfFile()
accepts return value from MapViewOfFile(),
not from CreateFileMapping(), like it is implemented in interactive
service. Interesting that in tun.c implementation
is correct.

It makes sense to move NULL assignment inside if { } to handle
unlikely case when the passed "ring" is NULL.
