windows: fix recvfrom and sendto data types

Fixes wrong data type used in Windows recvfrom and sendto calls

In Windows, `int` refers to a 32-bit signed integer
(https://docs.microsoft.com/en-us/windows/win32/winprog/windows-data-types#int).
However, the current implementation (https://golang.org/cl/208321)
uses the `int` type, which can have a different size. This is especially
important when recvfrom` returns a 32bit value of `-1`, indicating an error,
since it is interpreted as the 64bit value 4294967295.
