nfs_lib.sh: Unexport on proper side on netns

f6b2670 changed exportfs run locally on netns, therefore unexporting
should be also run at the same namespace. This is not problematic now,
but will be a problem with TST_ALL_FILESYSTEMS=1, which is sensitive for
timing.

Fixes: f6b2670 ("nfs_lib.sh: run exportfs at "server side" in LTP_NETNS case")
