Julian Heuking 304d469dcd Add missing dmu_zfetch_fini() in dnode_move_impl() 
As it turns out, on the Windows platform when rw_init() is called
(rather its bedrock call ExInitializeResourceLite) it is placed on
an active-list of locks, and is removed at rw_destroy() time.

dnode_move() has logic to copy over the old-dnode to new-dnode,
including calling dmu_zfetch_init(new-dnode). But due to the missing
dmu_zfetch_fini(old-dnode), kmem will call dnode_dest() to release the
memory (and in debug builds fill pattern 0xdeadbeef) over the Windows
active-lock's prev/next list pointers, making Windows sad.

But on other platforms, the contents of dmu_zfetch_fini() is one
call to list_destroy() and one to rw_destroy(), which is effectively
a no-op call and is not required. This commit is mostly for
"correctness" and can be skipped there.

Porting Notes:
* This leak exists on Linux but currently can never happen because
  the dnode_move() functionality is not supported.
