ws2_32: Add a comment to ioctlsocket about 'bogus' ioctl 0x667e.

[Dmitry Timoshkov]

Hello,

while inspecting socket IOCTL command values, I noticed a comment
in the 'default' case of WS_ioctlsocket about bogus ioctl 0x667e
which Netscape sends, and looked more closely what is that.

Changelog:
    ws2_32: Add a comment to ioctlsocket about 'bogus' ioctl 0x667e.
