softirq: remove irqs_disabled warning from local_bh_enable

There's no need to use local_irq_save() over local_irq_disable() in the
local_bh_enable code since it is a bug to call it with irqs disabled and
do_softirq will enable irqs if there is any pending work.

Consolidate the code from local_bh_enable and ..._ip to avoid having a
disconnect between them in the warnings they trigger that is currently
there.

Also always trigger the warning on in_irq(), not just in the
trace-irqflags case.
