[PATCH AUTOSEL 4.14 007/371] IB/rxe: replace kvfree with vfree

[Sasha Levin <sashal@kernel.org>]

From: Zhu Yanjun <yanjun.zhu@oracle.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")
