Dan McDonald 460a021391 Log zvol truncate/discard operations 
As the comments in zvol_discard() suggested, the discard operation
could be logged to the zil.  This is a port of the relevant code from
Nexenta as it was added in "701 UNMAP support for COMSTAR" and has been
attributed to the author of that commit.
