staging: android: ion: tegra: Use devm_kcalloc instead of devm_kzalloc

Browse source 
Replace devm_kzalloc with devm_kcalloc to ensure there are no integer
overflows from the multiplication of a number * sizeof.

The following Coccinelle semantic patch was used to make this change:
//<smpl>
@@
expression dev,E1,E3;
type T;
@@
- devm_kzalloc(dev,E1*sizeof(T),E3)
+ devm_kcalloc(dev,E1,sizeof(T),E3)
//</smpl>
