Bluetooth: Convert Pair Device to use cmd_complete callback
This patch converts the Pair Device mgmt command to use the new cmd_complete callback for pending mgmt commands. The already existing pairing_complete() function is exactly what's needed and doesn't need changing. In addition to getting the return parameters always right this patch actually fixes a reference counting bug and memory leak with the hci_conn that's attached to the pending mgmt command - something that would occur when powering off or unplugging the adapter while pairing is in progress.
