Subject: [PATCH 4.17 51/70] x86/vector: Fix the args of vector_alloc tracepoint

4.17-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dou Liyang <douly.fnst@...fujitsu.com>

commit 838d76d63ec4eaeaa12bedfa50f261480f615200 upstream.

The vector_alloc tracepont reversed the reserved and ret aggs, that made
the trace print wrong. Exchange them.

Fixes: 8d1e3dca7de6 ("x86/vector: Add tracepoints for vector management")
