media: siano: fix device register error path

[ Upstream commit 5368b1ee2939961a16e74972b69088433fc52195 ]

As reported by smatch:
	drivers/media/common/siano/smsdvb-main.c:1231 smsdvb_hotplug() warn: '&client->entry' not removed from list

If an error occur at the end of the registration logic, it won't
drop the device from the list.
