[GIT PULL] probes: Fixes for v6.14

[Masami Hiramatsu]

Hi Linus,

Probes fixes for v6.14:

- fprobe: Fix to remove fprobe_hlist_node when module unloading

  When a fprobe target module is removed, the fprobe_hlist_node
  should be removed from the fprobe's hash table to prevent reusing
  accidentally if another module is loaded at the same address.

- fprobe: Fix to lock module while registering fprobe

　The module containing the function to be probeed is locked using a
  reference counter until the fprobe registration is complete, which
  prevents use after free.

- fprobe-events: Fix possible UAF on modules

  Basically as same as above, but in the fprobe-events layer we also
  need to get module reference counter when we find the tracepoint
  in the module.
