Multiple export locations are shown during share migration

[Rodrigo Barbieri]

When migrating a share, multiple export locations are shown, while only the export location respective to the source instance is useful. There is no way the user can determine which one is related to the source.

    Fix multiple export locations during migration

    During a migration, the destination share instance export location
    was being shown, thus the user could get confused as to which
    export location to choose when mounting his share, since only
    the source could be mounted.

    This patch addresses this by filtering the destination
    export location out.
