[lm-sensors] [PATCH] hwmon/lm90: Quiet down error messages when probing

The commit "hwmon/lm90: Add support for the Maxim MAX6680/MAX6681"
added a number of new addresses to probe for lm90 devices, which for me
resulted in a bunch of these during boot (26 of them!):

Register 0xfe read failed (-1)
Register 0xfe read failed (-1)
Register 0xfe read failed (-1)

I.e. one for every failed probe -- 3 busses, 9 addresses.

No other hwmon driver prints debug info like this, so let's just get
rid of it.
