_aio_aqueue(): Change kevent registration to use its own struct file pointer.

Browse Source 
Otherwise, aio_read() and aio_write() on sockets are broken if a kevent is
 registered.  (The code after kevent registration for handling sockets assumes
 that the struct file pointer "fp" still refers to the socket, not the kqueue.)
