Subject: [PATCH 4.19 036/639] IB/rxe: replace kvfree with vfree

From: Zhu Yanjun <yanjun.zhu@...cle.com>

[ Upstream commit 721ad7e643f7002efa398838693f90284ea216d1 ]

The buf is allocated by vmalloc_user in the function rxe_queue_init.
So it is better to free it by vfree.

Fixes: 8700e3e7c485 ("Soft RoCE driver")
