Subject: [PATCH net-next 20/28] tipc: Remove redundant search when enabling bearer

From: Allan Stephens <allan.stephens@...driver.com>

Removes obsolete code that searches for an Ethernet bearer structure entry
to use for a newly enabled bearer, since this search is now performed
at the start of the enabling algorithm.
