Bluetooth: hci_check_conn_params() check proper range
Slave latency range has been changed in Core Spec. 4.2 by Erratum 5419
of ESR08_V1.0.0. And it should be applied to Core Spec. 4.0 and 4.1.
Before:
connSlaveLatency <= ((connSupervisionTimeout / connIntervalMax) - 1)
After:
connSlaveLatency <= ((connSupervisionTimeout / (connIntervalMax*2)) - 1)
This patch makes hci_check_conn_params() check the allowable slave
latency range using the changed way.
