Bluetooth: hci_event: Fix not handling PA Sync Lost event

Browse Source 
This handles PA Sync Lost event which previously was assumed to be
handled with BIG Sync Lost but their lifetime are not the same thus why
there are 2 different events to inform when each sync is lost.

Fixes: b2a5f2e1c1 ("Bluetooth: hci_event: Add support for handling LE BIG Sync Lost event")
