Rodrigo Barbieri 53b91e513e 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.
