double use of indices in SPH density loop

Dear gadget-list members,

I just noticed that during the computation of the SPH density, there is
a possibly dangerous double use of loop indices.
First note that the loop over the workstack for doing final operations
on the results uses the index "i":|

    |for(int i = 0; i < ndensities; i++)|

|later in the same loop when hfac is computed using a loop, it is
indexed with the same "i":|||

    ||for(int i = 0; i < NUMDIMS; i++)||

||This could potentially lead to problems and should be changed to
something else (like "j").||
