Input: evdev - call input_flush_device() on release(), not flush()
input_flush_device() should only be called once the struct file is being
released and no open descriptors remain, but evdev_flush() was calling
it whenever a file descriptor was closed.
This caused uploaded force-feedback effects to be erased when a process
did a dup()/close() on the event FD, called system(), etc.
Call input_flush_device() from evdev_release() instead.
