Kuba Pawlak 618353b1f3 Bluetooth: Fix SCO link type handling on connection complete 
Synchronous connections are initially created with type eSCO.
Link manager may reject proposed link parameters, which triggers
connection setup retry with a different set. Link type embedded
in responses should be disregarded until Synchronous Connect Complete
returns Success (0x00). Current code updates link type every time
which creates an issue when link type changes to SCO and back to eSCO
on further attepts.

Issue happens with BlackBerry 9100 and 9700 with Intel WilkinsPeak
on third connection setup attept
