Alex Brainman fca3dd3718 syscall: avoid convT2I allocs for ERROR_IO_PENDING instead of WSAEINPROGRESS
CL 28484 mistakenly assumed that WSARecv returns WSAEINPROGRESS
when there is nothing to read. But the error is ERROR_IO_PENDING.
Fix that mistake.

I was about to write a test for it. But I have found
TestTCPReadWriteAllocs in net package that does nearly what I need,
but was conveniently disabled. So enable and extend the test.

Fixes #16988

Our canonical Git repository is located at https://go.googlesource.com/go. There is a mirror of the repository at https://github.com/golang/go.

Go is the work of hundreds of contributors. We appreciate your help!

Binary Distribution Notes

If you have just untarred a binary Go distribution, you need to set the environment variable $GOROOT to the full path of the go directory (the one containing this file). You can omit the variable if you unpack it into /usr/local/go, or if you rebuild from sources by running all.bash (see doc/install-source.html). You should also add the Go binary directory $GOROOT/bin to your shell's path.

For example, if you extracted the tar file into $HOME/go, you might put the following in your .profile:

export GOROOT=$HOME/go
export PATH=$PATH:$GOROOT/bin

See https://golang.org/doc/install or doc/install.html for more details.
