Subject: [PATCH] IB/rdmavt: free the userspace memory region with kfree instead of vfree

From: Colin Ian King <colin.king@...onical.com>

The userspace memory region 'mr' is allocated with kzalloc in
__rvt_alloc_mr  however it is incorrectly being freed with vfree in
__rvt_free_mr. Fix this by using kfree to free it.
