[PATCH 2/5] IB/qib: Use kmalloc_array() in qib_init_7322_variables()

From: Markus Elfring <elfring@users.sourceforge.net>

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.
