Bluetooth: Fix memory leak in le_scan_disable_work_complete()
The hci_request in le_scan_disable_work_complete() was being initialized in a general context but only used in a specific branch in the function (when simultaneous discovery is not supported). This patch moves the usage to be limited to the branch where hci_req_run() is actually called.
