[PATCH 1/1] scripts: fix cscope breakage

[Jiri Slaby]

Commit 66979224c0d2 (scripts: refactor remove structure forward
declarations) introduced a breakage in tags.sh for others than tags.
So make cscope now fails with:
sed: can't read cscope: No such file or directory

Fix it by quoting remove_structs properly.

Guys, for how long has this been in -next? I update -next and run
cscope once a week and this issue is new this week. And the patch is
already in -rc1? WTF?
