[PATCH 1/3] target: configfs: preserve the error from fabric_make_np()

[shao.mingyin]

From: Shao Mingyin <shao.mingyin@xxxxxxxxxx>

target_fabric_make_np() replaces every error pointer returned by the
fabric callback with -EINVAL.  Return the original error.

Fixes: c66ac9db8d4ad ("[SCSI] target: Add LIO target core v4.0.0-rc6")
