Miklos Szeredi a9bce5fed6 fuse: fix possibly missing fuse_copy_finish() call in fuse_notify() ...

commit 0b563aad1c upstream.

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: 760eac73f9 ("fuse: Introduce a new notification type for resend pending requests")
Fixes: 2396356a94 ("fuse: add more control over cache invalidation behaviour")
