RFR : 8051614 : smartcardio TCK tests fail due to lack of 'reset' permission

[Seán Coffey]

A recent fix was introduced to preserve the behaviour of an old buggy 
implementation of smartcardio Card.disconnect :
https://bugs.openjdk.java.net/browse/JDK-8049250

The old behaviour is not fully restored with this flag if a security 
manager lacking sufficient permissions is present. This could disrupt 
legacy applications which may wish to rely on the old behaviour. Some 
internal testing has also highlighted this.

To enhance the 8049250 fix, I'm proposing we delay the boolean flip 
operation until post the security check.

Bug report is not public due to internal links and servers being present 
in description.

I'd like to get this into JDK 9 and 8u20.

regards,
Sean.
