Johan Hovold 2ad5692db7 net: hso: fix NULL-deref on disconnect regression 
Commit 8a12f88361 ("net: hso: fix null-ptr-deref during tty device
unregistration") fixed the racy minor allocation reported by syzbot, but
introduced an unconditional NULL-pointer dereference on every disconnect
instead.

Specifically, the serial device table must no longer be accessed after
the minor has been released by hso_serial_tty_unregister().

Fixes: 8a12f88361 ("net: hso: fix null-ptr-deref during tty device unregistration")
