target: Use kmalloc_array() in transport_kmap_data_sg()
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. Signed-off-by: Markus Elfring <elfring@users.sourceforge.net> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
