[PATCH] Bluetooth: Fix command complete/status for discovery commands

[johan.hedberg@gmail.com]

From: Johan Hedberg <johan.hedberg@intel.com>

This patch adds the necessary code to send proper command status or
command complete events to the start/stop discovery management commands.
Before this patch these events were completely missing.
