Switchover Fails if Replicated FS Exported & Mountpoint Can be Overwritten (25970289)

Problem Summary: A protection group switchover fails if replicated filesystems from a project in the protection group are exported. Also, if such a filesystem is exported and its mountpoint changed, this results in mountpoint getting overwritten.

Workaround: If you must export replicated filesystems, you must stop exporting them before a switchover. In addition, if the mountpoint of the exported replicated filesystems is changed, you must set it to the same mountpoint of the source before the switchover.
