Bluetooth: hci_conn: Fix running bis_cleanup for hci_conn->type PA_LINK

Browse Source 
Connections with type of PA_LINK shall be considered temporary just to
track the lifetime of PA Sync setup, once the BIG Sync is established
and connection are created with BIS_LINK the existing PA_LINK
connection shall not longer use bis_cleanup otherwise it terminates the
PA Sync when that shall be left to BIS_LINK connection to do it.

Fixes: a7bcffc673 ("Bluetooth: Add PA_LINK to distinguish BIG sync and PA sync connections")
