device: handle broader range of errors in RoutineReceiveIncoming

Browse Source 
RoutineReceiveIncoming exits immediately on net.ErrClosed,
but not on other errors. However, for errors that are known
to be permanent, such as syscall.EAFNOSUPPORT,
we may as well exit immediately instead of retrying.

This considerably speeds up the package device tests right now,
because the Bind sometimes (incorrectly) returns syscall.EAFNOSUPPORT
instead of net.ErrClosed.
