[PATCH BlueZ v1 2/2] btdev: Fix double lookup

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

From: Luiz Augusto von Dentz <luiz.von.dentz@xxxxxxxxx>

This fixes the existing double lookup when calling
num_completed_packets but passing the conn->handle instead of passing
the conn pointer directly since num_completed_packets would then attempt
to do another lookup by handle to resolve the conn pointer again.
