[PATCH v2 3/3] system/os-win32: Remove unnecessary 'qemu/typedefs.h' include

[Philippe Mathieu-Daudé]

Commit f5fd677ae7c ("win32/socket: introduce qemu_socket_select()
helper") included the "qemu/typedefs.h" header for the Error type,
but files including "system/os-win32.h" should already include
"qemu/osdep.h", and thus "qemu/typedefs.h".

Amusingly qemu_socket_[un]select() are always called with Error=NULL.
