soc: ti: ti_sci_pm_domains: Check for null return of devm_kcalloc
The allocation funciton devm_kcalloc may fail and return a null pointer, which would cause a null-pointer dereference later. It might be better to check it and directly return -ENOMEM just like the usage of devm_kcalloc in previous code.
