Pavel Zakharov e6cebbf86e zfs_handle used after being closed/freed in change_one callback
This is a typical case of use after free. We would call zfs_close(zhp) 
which would free the handle, and then call zfs_iter_children() on that 
handle later.  This change ensures that the zfs_handle is only closed 
when we are ready to return.

Running `zfs inherit -r sharenfs pool` was failing with an error
code without any error messages. After some debugging I've pinpointed 
the issue to be memory corruption, which would cause zfs to try to 
issue an ioctl to the wrong device and receive ENOTTY.
