Subject: [PATCH v2] target: remove initiatorname field in se_acl_lun

From: Chris Zankel <czankel@...estorage.com>

The initiatorname field in se_acl_lun is only a copy of the same field
in se_node_acl, so remove it and use the version in se_node_acl where
needed (it's actually only used for pr_debug)
