ws2_32: Fix a memory leak on WS2_AcceptEx

After some tests I found out wsa->read is not being freed (2 HeapAllocs, 1
HeapFree on the function). The attached patch fixes this.

I tried playing around with valgrind but I can't get any valgrind output using
the following command inside ws2_32\tests (before or after the patch):

valgrind --tool=memcheck --leak-check=yes ../../../tools/runtest -p
ws2_32_test.exe.so sock

Can anyone retest or teach me how to test correctly on valgrind?
Thanks in advance.
