irmd, ipcp: Remove socket option in acceptloop

We cancel the thread, so the SO_RCVTIMEO is not needed anymore (it
dated from when we checked the state every so often.

The address sanitizer is complaining about the the cleanup handlers in
the acceptloops after the thread gets cancelled in the read(). I've
tried to resolve it, but no avail. Pretty convinced it's a
false-positive, so ASan will ignore these functions for now.
