[Virtio-fs] [PATCH 1/2] fuse: drop unused struct fuse_setupmapping_out

[Stefan Hajnoczi <stefanha@redhat.com>]

Originally the idea was that FUSE_SETUPMAPPING returns a list of
addresses where the mmaps were made.  But then we decided to let the
FUSE client decide where to map so it already knows the address.
Consequently this struct is unused.
