[PATCH rdma-rc v1] IB/uverbs: Declare local function to be static and add brackets to sizeof

[PATCH rdma-rc v1] IB/uverbs: Declare local function to be static and add brackets to sizeof

[Leon Romanovsky]

From: Leon Romanovsky <leonro-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>

Commit 57520751445b ("IB/SA: Add OPA path record type") introduced
new local function __ib_copy_path_rec_to_user, but didn't limit its
scope. This produces the following sparse warning:

	drivers/infiniband/core/uverbs_marshall.c:99:6: warning:
	symbol '__ib_copy_path_rec_to_user' was not declared. Should it be
	static?

In addition, it used sizeof ... notations instead of sizeof(...), which
is correct in C, but a little bit misleading. Let's change it too.

Fixes: 57520751445b ("IB/SA: Add OPA path record type")
