[SRU HWE-5.17 1/1] net: rose: fix UAF bugs caused by timer handler

[Thadeu Lima de Souza Cascardo]

I wonder if we need 148ca04518070910739dfc4eeda765057856403d ("net: rose:
fix UAF bug caused by rose_t0timer_expiry") as well or if this just
warrants yet another CVE.

Can you open a bug and make sure that one is included everywhere?

Cascardo.
