Background page replacement logic adds a new anonymous page
instead of a file backed (while inserting a breakpoint) /
anonymous page (while removing a breakpoint).
Hence the uprobes logic should take care to update the
task->ss_stat counters accordingly.
This bug became apparent courtesy of commit c3f0327f8e9d
("mm: add rss counters consistency check").
