HID: amd_sfh: don't log error when device discovery fails with -EOPNOTSUPP

Browse Source 
[ Upstream commit 743677a8cb ]

When sensor discovery fails on systems without AMD SFH sensors, the
code already emits a warning via dev_warn() in amd_sfh_hid_client_init().
The subsequent dev_err() in sfh_init_work() for the same -EOPNOTSUPP
return value is redundant and causes unnecessary alarm.

Suppress the dev_err() for -EOPNOTSUPP to avoid confusing users who
have no AMD SFH sensors.
