Fix : Null deference issue

[Problem] If remote device is not connected but _bt_le_conn_update is
 called, crash happens.
[Cause & Measure] There is no connected device info. But it is
 deferenced. This patch checks NULL for connected device info.
[Checking Method] Try to update LE connection parameter to non-connected
 BLE device
