[PATCH] VMCI: Use kmalloc_array() in qp_alloc_ppn_set()
From: SF Markus Elfring

Multiplications for the size determination of memory allocations
indicated that array data structures should be processed.
Thus use the corresponding function "kmalloc_array".
This issue was detected by using the Coccinelle software.
