hfsplus: stop workqueue when fill_super() failed
syzbot is reporting ODEBUG messages at hfsplus_fill_super() [1]. This
is because hfsplus_fill_super() forgot to call cancel_delayed_work_sync().
As far as I can see, it is hfsplus_mark_mdb_dirty() from
hfsplus_new_inode() in hfsplus_fill_super() that calls
queue_delayed_work(). Therefore, I assume that hfsplus_new_inode() does
not fail if queue_delayed_work() was called, and the out_put_hidden_dir
label is the appropriate location to call cancel_delayed_work_sync().
