RFR [8048080] (smartcardio) javax.smartcardio.Card.openLogicalChannel() dosn't work on MacOSX

[Ivan Gerasimov]

Hello!

This bug is very similar to JDK-7195480, in the sense it is due to the 
structure misalignment under MacOSX.
I didn't fix it together with JDK-7195480 because I hadn't had a 
testcase in hands at that time to verify the change.
Now, I've got a testcase from SQE and it confirms the change is good.

Would you please help review the fix?
