At enslavement time, the primary slave might not be activated if there is already an active slave and the new slave is the primary. Replaced complicated logic with a call to bond_select_active_slave(), which does the right thing. Fixes http://bugzilla.kernel.org/show_bug.cgi?id=6378 Signed-off-by: Jay Vosburgh <redacted>
