Kir Kolyshkin 73baee2dcf integration-cli: fix netns test cleanup
1. Using MNT_FORCE flag does not make sense for nsfs. Using MNT_DETACH
though might help.

2. When -check.vv is added to TESTFLAGS, there are a lot of messages
like this one:

> unmount of /tmp/dxr/d847fd103a4ba/netns failed: invalid argument

and some like

> unmount of /tmp/dxr/dd245af642d94/netns failed: no such file or directory

The first one means directory is not a mount point, the second one
means it's gone. Do ignore both of these.
