iwlwifi: remove module loading failure message
[ Upstream commit 6518f83ffa51131daaf439b66094f684da3fb0ae ]
When CONFIG_DEBUG_TEST_DRIVER_REMOVE is set, iwlwifi crashes
when the opmode module cannot be loaded, due to completing
the completion before using drv->dev, which can then already
be freed.
Fix this by removing the (fairly useless) message. Moving the
completion later causes a deadlock instead, so that's not an
option.
