Local fix

Problem summary

• IBMPKCS11Impl provider intermittently was performing a
  cryptographic operation on a hardware session that has already
  been closed.  This could result in, "Session handle is invalid",
  "session has been closed" or other such errors.
  

Problem conclusion

• IBMPKCS11Impl provider was not clearing out the connection
  between the software session and the hardware security module
  (HSM) when the it closed the connection.  Later on, the HSM
  device would reuse the same session for a new connection.
  Garbage collection when it ran to clear out unused software
  session would call the IBMPKCS11Impl session finalize method to
  ensure that the connection to the HSM was closed.  This
  sometimes caused active connections to be closed, because the
  HSM could not differentiate that the connection called out in
  the garbage collection method was different than an active
  connection.
  IBMPKCS11Impl provider to clear out the connection information
  regarding the HSM when it closes the connection so that the
  finalize method knows that there is no hardware session to
  close.
