ANDROID: fuse: Support errors from fuse daemon in canonical path

Previously errors from the daemon in FUSE_CANONICAL_PATH were simply
ignored. In order to block inotifys, it is useful to be able to return
errors from this opcode.

Bug: 238619640
Test: inotify no longer works on /storage/emulated/0/Android/media but
      does on child folders
