In case of FUSE_NOTIFY_RESEND and FUSE_NOTIFY_INC_EPOCH fuse_copy_finish()
isn't called.
Fix by always calling fuse_copy_finish() after fuse_notify(). It's a no-op
if called a second time.
Fixes: 760eac73f9f6 ("fuse: Introduce a new notification type for resend pending requests")
Fixes: 2396356a945b ("fuse: add more control over cache invalidation behaviour")
