[PATCH v4 45/54] tests/qtest: libqtest: Replace the call to close a socket with closesocket()

[Bin Meng]

From: Bin Meng <bin.meng@windriver.com>

close() is a *nix function. It works on any file descriptor, and
sockets in *nix are an example of a file descriptor.

closesocket() is a Windows-specific function, which works only
specifically with sockets. Sockets on Windows do not use *nix-style
file descriptors, and socket() returns a handle to a kernel object
instead, so it must be closed with closesocket().

In QEMU there is already a logic to handle such platform difference
in os-posix.h and os-win32.h, that:

  * closesocket maps to close on POSIX
  * closesocket maps to a wrapper that calls the real closesocket()
    on Windows

Replace the call to close a socket with closesocket() instead.
