IB/hns: Use kmalloc_array() in hns_roce_cmd_use_events()
* A multiplication for the size determination of a memory allocation indicated that an array data structure should be processed. Thus use the corresponding function "kmalloc_array". This issue was detected by using the Coccinelle software. * Replace the specification of a data structure by a pointer dereference to make the corresponding size determination a bit safer according to the Linux coding style convention.
