fuse: make sure dentry is evicted if stale
d_dispose_if_unused() may find the dentry with a positive refcount, in
which case it won't be put on the dispose list even though it has already
timed out.
"Reinstall" the d_delete() callback, which was optimized out in
fuse_dentry_settime(). This will result in the dentry being evicted as
soon as the refcount hits zero.
Fixes: ab84ad597386 ("fuse: new work queue to periodically invalidate expired dentries")
