lockdep: Rename trace_{hard,soft}{irq_context,irqs_enabled}()

Continue what commit:

  d820ac4c2fa8 ("locking: rename trace_softirq_[enter|exit] => lockdep_softirq_[enter|exit]")

started, rename these to avoid confusing them with tracepoints.

git grep -l "trace_\(soft\|hard\)\(irq_context\|irqs_enabled\)" | while read file;
do
	sed -ie 's/trace_\(soft\|hard\)\(irq_context\|irqs_enabled\)/lockdep_\1\2/g' $file;
done
