1. Udev rules: remove zvol compat symlinks (without the leading zvol/) …

   This is a potentially arguable change, because it removes some
   compatibility cruft that certain systems or people may have come to rely
   on (either a very long time ago, or unwisely in recent times).
   
   On the other hand, it's been literally over a decade since OpenZFS
   switched to the strategy of using opaque numbered /dev/zd* device nodes,
   with the canonical zvol access path being a directory tree of symlinks
   created by udev rules inside /dev/zvol/*. (See openzfs#102.) Even at the time,
   the /dev/* scheme was labeled as being for "compatibility".
   
   This commit removes the second tree of symlinks located directly at
   /dev/*, under the assumption that anybody with any sense has been using
   the intended /dev/zvol/* path for a very very long time now.
   
   (The more I think about this, the more I anticipate that some large
   fraction of people will have been blissfully unaware that the intention
   has been for them to use the /dev/zvol/* tree all along, and they will
   have come to rely upon the /dev/* tree simply because it's been there
   this whole time despite being a compat thing.)
