Brian Behlendorf 5915791096 Move iput() after zfs_inode_update()
When replaying an unlink/remove operation via zfs_rmdir() the object
being removed will be instantiated by a call to zfs_dirent_lock().
This means that there is a single reference protecting the object.
Right before the call to zfs_inode_update() this reference is dropped
which may cause the object to be destroyed.  This will result in a
NULL dereference as shown by the stack trace is issue #782.

This likely isn't an issue during normal operation because there is
always an additional reference held on the object by the VFS.

Closes #782
