Fix EIO after resuming receive of new dataset over an existing one
When resuming an interrupted ZFS send stream that creates a new dataset
with the same name as an existing dataset, if the existing dataset is
accessed after the failed receive, then after the subsequent successful
receive it will return EIO. This happens because nothing mounts the new
dataset, leaving the old, no longer valid dataset still mounted.

This commit fixes zfs receive to always unmount and remount the
destination, regardless of whether the stream is a new stream or a
resumed stream.
