Bluetooth: Fix NULL pointer deference on eir_get_service_data

[ Upstream commit 20a2aa01f5aeb6daad9aeaa7c33dd512c58d81eb ]

The len parameter is considered optional so it can be NULL so it cannot
be used for skipping to next entry of EIR_SERVICE_DATA.

Fixes: 8f9ae5b3ae80 ("Bluetooth: eir: Add helpers for managing service data")
