Subject: [PATCH] PQhost update to return proper host details

Earlier PQhost doesn't return the connected host details
when the connection type is CHT_HOST_ADDRESS instead it
returns the provided connection host parameter or the default
host details.

Providing specified connection host parameter or default host
leads to use confusion, it is better to provide the host details
of the connected host irrespective of the connection type
if exists.
