ID:319 - Interface safe re-open

Currently, interface-management code in the ipmitool does not allow safe
interface re-opening (i.e. closing and opening again). It is because the session
is allocated in the interface setup callback while is freed in the close
callback. So, normal re-opening of the interface, which can be required for
example durng the HPM.1 upgrade, leads to segmentation fault. That's why in the
ipmi_hpmfwupg.c instead of normal closing interface, directly access the
interface data for subsequent re-opening.
