The net package consists of thin three layers like the follwoing;

- Exposed API, that contains net.Dial, net.DialUDP, net.DialUnix
- Socket and network file descriptor, that contains net.netFD and
  its methods, helper functions such as dialUDP, dialUnix
- Network pollster, that contains net.pollDesc and its methods

This CL removes redundant argument check which is already done by
API layer.

pointer.  An example that triggers the bad behavior on a 64bit
machine http://play.golang.org/p/GrNFakAYLN

        rv3.Set(rv2)

Running the code fails with the following:
        panic: reflect: internal error: storeIword of 16-byte value

I've tested on a 64bit machine and verified this fixes the panic.  I
haven't tested on a 32bit machine so I haven't verified the other
cases, but they follow logically.
