net: lwm2m: Remove misused errno check

Browse source 
Errno value is only significant when `recvfrom` function indicated an
error (by returning -1). We should not depend on it's value if no error
is notified.

As the return value of `recvfrom` is already checked, misused errno
verification can simply be removed.
