thermal/int340x_thermal: Prevent page fault on .set_mode() op
Starting from commit "thermal/int340x_thermal: Don't require IDSP to
exist", priv->current_uuid_index is initialized to -1. This value may
be passed to int3400_thermal_run_osc() from int3400_thermal_set_mode,
contributing to page fault when accessing int3400_thermal_uuids array
at index -1.
This commit adds a check on uuid value to int3400_thermal_run_osc.
