FROMLIST: Bluetooth: Tolerate valid pre 4.2 conn params
This patch tolerates connection parameters that were valid before
ESR08_v1.0.0 which was also incoporated into the 4.2 core specification.
In particular, this addresses compatibility issues with the Lenovo Yoga
Mouse that sees its connection parameters rejected by the max_latency
computation in hci_conn_check_params, but was perfectly valid at the
time this mouse was qualified.
Before the patch, the mouse was extremely laggy, after the patch, the
mouse worked as expected.
