[Bug runtime/6488] New: remove unnecessary locking in print paths

[fche at redhat dot com]

runtime/print* and callees has several spinlock/irqsave calls.

When called from systemtap probes, these are not necessary since
irq's etc. are already all disabled, so we're wasting time.

If there exist other callers (module startup/shutdown yak perhaps),
these should be modified to include lock/unlock wrappers to
emulate probe-handler (atomic) context.
