[RESTRICT AUTOMERGE] Close the logical channel after opening it

The test case android.telephony4.cts.SimReswstrictedApisTest#testIccOpenLogicalChannel
is supposed to fail so that no logical channel will be opened. However, if under any
circumstances this test doesn't fail, we need to make sure the opened logical channel
is closed.

Test: run cts --module CtsTelephonyTestCases
