Subject: [PATCH AUTOSEL 4.14 44/87] s390/dasd: correct numa_node in
 dasd_alloc_queue

From: Vasily Gorbik <gor@...ux.ibm.com>

[ Upstream commit b17e3abb0af404cb62ad4ef1a5962f58b06e2b78 ]

The numa_node field of the tag_set struct has to be explicitly
initialized, otherwise it stays as 0, which is a valid numa node id and
cause memory allocation failure if node 0 is offline.
