parentATM-ZeitNet: Improve a size determination in zatm_open() (diff)

ATM-ZeitNet: Replace one kzalloc() call by kcalloc()
* The script "checkpatch.pl" can point information out like the following. WARNING: Prefer kcalloc over kzalloc with multiply Thus fix the affected source code place. * Replace the specification of a data type by a pointer dereference to make the corresponding size determination a bit safer according to the Linux coding style convention. * Delete the local variable "size" which became unnecessary with this refactoring.
