Subject: [PATCH] Documentation/vm/page_owner.rst: fix the description of "-f"

Few days ago,
I noticed that in tools/vm/page_owner_sort.c,
there is a comment that need to be fixed.

In function usage():
"-f Filter out the information of blocks whose memory has
not been released."

This comment does not match the actual function, the "not"
should be removed. As a result, I submitted a patch to fix it.

Similarly, this document should also do the same
modification, that's why I submit this patch.
