Bluetooth: Disable sniff when the subrate values doesnt match.
Found there is possibility of sniff subrate collision with some
IOT devices. When this collision happned if the remote device
send subrate values that doesn't match with DUT supported
values exit sniff mode. This will allow DUT to reconfigure
sniff after idle time.
