tcp_bbr: fix SPDX-License-Identifier to be GPL-2.0 OR BSD-3-Clause

Since TCP BBR congestion control was introduced in
commit 0f8782ea1497 ("tcp_bbr: add BBR congestion control")
it has always been offered as "Dual BSD/GPL":

  MODULE_LICENSE("Dual BSD/GPL");

A GPL-2.0-only SPDX header was erroneously added in the recent
commit 2ed4b46b4fc7 ("net: Add SPDX ids to some source files").

This commit revises the tcp_bbr.c SPDX-License-Identifier to note that
this file is licensed as "GPL-2.0 OR BSD-3-Clause".
