[PATCH v17 2/3] ws2_32: Access internal fields of WSAOVERLAPPED as IO_STATUS_BLOCK.

[Jinoh Kang]

From: Jinoh Kang

Make it clear that we're accessing an IO_STATUS_BLOCK.

Don't rely on the little endian representation of the Internal field on
64-bit build, when we're in fact accessing the Status field.
