Subject: [PATCH 12/21] target: Fix bogus return in transport_add_device_to_core_hba failure path

From: Nicholas Bellinger <nab@...ux-iscsi.org>

This patch removes a bogus conditional+return check within the failure path
of transport_add_device_to_core_hba().  This breakage was introduced during
the v4 conversion to remove struct se_cmd passthrough ops for INQUIRY /
READ_CAPCITY during struct se_device creation and registration process.
