fuse: no ENOENT from fuse device read
Don't return -ENOENT for a read() on the fuse device when the request was aborted. Instead return -ENODEV, meaning the filesystem has been force-umounted or aborted. Previously ENOENT meant that the request was interrupted, but now the 'aborted' flag is not set in case of interrupts.
