Subject: [PATCH 2/6] [Target_Core_Mod/ALUA]: Add setup for target_core_device.c code
This patch will attach a give se_port_t to the default Target Port Group
in core_export_port() when SPC3_ALUA_EMULATED is enabled.
Also, add core_release_port() and se_free_virtual_device() for releasing
associated Target Port Group and Logical Unit Group assoicaton respectively
in release paths.
