bonding: don't lock when copying/clearing VLAN list on slave
When copying VLAN information to or removing from a slave
during slave addition or removal, the bonding code currently holds
the bond->lock for write to prevent concurrent modification of the
vlan_list / vlgrp.
This is unnecessary, as all of these operations occur under
RTNL. Holding the bond->lock also caused might_sleep issues for
some drivers' ndo_vlan_* functions. This patch removes the extra
locking.
