fanotify: add an extra flag to mark_remove_from_mask that indicates wheather a mark should be destroyed

This patch adds an extra flag to mark_remove_from_mask() to inform the caller if
the mark should be destroyed.
With this we dont destroy the mark implicitly in the function itself any more
but let the caller handle it.
