net: bonding: fix tlb_dynamic_lb default value
Commit 8b426dc54cf4 ("bonding: remove hardcoded value") changed the default value for tlb_dynamic_lb which lead to either broken ALB mode (since tlb_dynamic_lb can be changed only in TLB) or setting TLB mode with tlb_dynamic_lb equal to 0. The first issue was recently fixed by setting tlb_dynamic_lb to 1 always when switching to ALB mode, but the default value is still wrong and we'll enter TLB mode with tlb_dynamic_lb equal to 0 if the mode is changed via netlink or sysfs. In order to restore the previous behaviour and default value simply remove the mode check around the default param initialization for tlb_dynamic_lb which will always set it to 1 as before.
