commit 95c9f4d4da6c4e445a9dd58c8382356520ea91a0
[SCSI] libsas: use right function to alloc smp response

In fact the disc_resp buffer will be overwrite by smp response, so we never
found this typo, correct it by using the right one.

It corrects stupid typo:
-    disc_resp = alloc_smp_req(DISCOVER_RESP_SIZE);
+    disc_resp = alloc_smp_resp(DISCOVER_RESP_SIZE);
