bridge: fix netconsole setup over bridge
[ Upstream commit dbe173079ab58a444e12dbebe96f5aec1e0bed1a ] Commit 93d8bf9fb8f3 ("bridge: cleanup netpoll code") introduced a check in br_netpoll_enable(), but this check is incorrect for br_netpoll_setup(). This patch moves the code after the check into __br_netpoll_enable() and calls it in br_netpoll_setup(). For br_add_if(), the check is still needed.
