[PATCH 04/19] thunderbolt: Do not overwrite error code when domain adding fails

[Anthony Wong]

From: Mika Westerberg <mika.westerberg at linux.intel.com>

If the Thunderbolt domain adding fails for some reason we currently
always return -EIO instead of the real error code. To make debugging
easier return the actual error code instead.
