thermal: core: prevent potential string overflow

[ Upstream commit c99626092efca3061b387043d4a7399bf75fbdd5 ]

The dev->id value comes from ida_alloc() so it's a number between zero
and INT_MAX.  If it's too high then these sprintf()s will overflow.

Fixes: 203d3d4aa482 ("the generic thermal sysfs driver")
