Bluetooth: ISO: Fix not using SID from adv report

Bluetooth: ISO: Fix not using SID from adv report

Up until now it has been assumed that the application would be able to
enter the advertising SID in sockaddr_iso_bc.bc_sid, but userspace has
no access to SID since the likes of MGMT_EV_DEVICE_FOUND cannot carry
it, so it was left unset (0x00) which means it would be unable to
synchronize if the broadcast source is using a different SID e.g. 0x04:

> HCI Event: LE Meta Event (0x3e) plen 57

        Num reports: 1

        SID: 0x00 (<- Invalid)
        Adv address type: Random (0x01)
        Adv address: 0B:82:E8:50:6D:C8 (Non-Resolvable)

        Sync timeout: 20000 msec (0x07d0)
        Sync CTE type: 0x0000

So instead this changes now allow application to set HCI_SID_INVALID
which will make hci_le_pa_create_sync to wait for a report, update the
conn->sid using the report SID and only then issue PA create sync
command:
