Subject: [PATCH] HID: amd_sfh: Don't show client init failed as error when discovery fails

When sensor discovery fails, this means that the system doesn't have
any sensors connected and a user should only be notified at most one time.
A message is already displayed at WARN level of "failed ot discover,
sensors not enabled".  It's pointless to show that the client init failed
at ERR level for the same condition.

Check the return code and don't display this message in thoes conditions.

Fixes: b5d7f43e97da ("HID: amd_sfh: Add support for sensor discovery")
