spacemanager: bug fix. Always remove file from srmspacefile table

   commit f03d1d73fdf79f066a90ac5be2d20ae8ded760f9 introduced a bug:
   a boolean variable that previously has always been true, was set to
   false exposing undesirable code path resulting in deleted files
   not being removed from srmspacefile table. Since this variable has never
   been exposed to users this patch simply excised code that deals with
   the variable. Issue existed only on the head.
