[Bridge] [PATCH 3+/4] bridge: fix locking of set path cost

[Stephen Hemminger <shemminger@linux-foundation.org>]

This change goes with earlier change to get rid of 
work queue for path cost. Now stp_set_path_cost does its own
locking. This is to allow it to call br_path_cost() which calls
ethtool interfaces (might sleep).
