win32: drop fd registration to the main-loop on setting non-block

Low-level fd users from QEMU use aio_set_fd_handler(), which handles
event registration with the main loop; qemu_fd_register() is only
needed together with the main loop's poll notifiers, of which SLIRP
is the only user.

This removes a dependency from oslib-win32.c to main-loop.c.
