[Libguestfs] [PATCH] upload: improve file write callback

[Matteo Cafasso]

As noted by Pino in another patch, the logic passes the first member of
the struct which happens to be the right address to the callback
function.

This will break the callback if order of the members of the struct will
change.

As the callback is using the entire struct, better to pass the pointer
to the struct itself.
