[PATCH] thermal: intel: hfi: Remove a pointless die_id check

[PATCH] thermal: intel: hfi: Remove a pointless die_id check

[Ricardo Neri]

die_id is an u16 quantity. On single-die systems the default value of
die_id is 0. No need to check for negative values.

Plus, removing this check makes Coverity happy.
