[PATCH 1/7] Bluetooth: Add convenience function for getting total connection count

[johan.hedberg@gmail.com]

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

This patch adds a convenience function to return the number of
connections in the conn_hash list. This will be useful once we update
the power off procedure to disconnect any open connections.
