debugfs: fix use-after-free on symlink traversal
[ Upstream commit 93b919da64c15b90953f96a536e5e61df896ca57 ]
symlink body shouldn't be freed without an RCU delay. Switch debugfs to
->destroy_inode() and use of call_rcu(); free both the inode and symlink
body in the callback. Similar to solution for bpf, only here it's even
more obvious that ->evict_inode() can be dropped.
