Li Zefan e8082f3f5a tracing/filters: don't remove old filters when failed to write subsys->filter ...

If writing subsys->filter returns EINVAL or ENOSPC, the original
filters in subsys/ and subsys/events/ will be removed. This is
definitely wrong.

[ Impact: fix filter setting semantics on error condition ]
