thermal/debugfs: replace kzalloc() with kcalloc() in thermal_debug_tz_add()

Browse Source 
Work is under way to get rid of all multiplications from allocation
functions to prevent integer overflows [1].

Here the multiplication is obviously safe, but using kcalloc() is more
appropriate and improves readability.

This change has no effect on runtime behavior.
