jump label: Remove static_branch()
Remove the obsolete static_branch() interface, since the supported interface is now static_key_false()/true() - which is used by all in-tree code. See commit: c5905afb0e ("static keys: Introduce 'struct static_key', static_key_true()/false() and static_key_slow_[inc|dec]()").
