[PATCH v6 16/23] Bluetooth: hci_sync: Convert MGMT_OP_READ_LOCAL_OOB_EXT_DATA

[Luiz Augusto von Dentz <luiz.dentz@gmail.com>]

From: Brian Gix <brian.gix@intel.com>

Uses existing *_sync functions

mgmt-test paths:
Read Local OOB Ext Data - Invalid index
Read Local OOB Ext Data - Legacy pairing
Read Local OOB Ext Data - Success SSP
Read Local OOB Ext Data - Success SC
