fs/fuse kio: do not return -EINVAL from fuse_dev_do_write() on killed
request.
It is a normal scenario that the request may have been killed when a
response is returned. So we shouldn't return -EINVAL to the response
writer, just need to complete the request with error. Otherwise it
breaks the userspace thread.
