tracing: convert irq trace points to new macros
Impact: enhancement Converted the two irq trace point macros. The entry macro copies the name of the irq handler, thus it is better to simply use the TRACE_FORMAT macro which uses the trace_printk. The return of the handler does not need to record the name, thus the faster C style handler is more approriate. Signed-off-by: Steven Rostedt <srostedt@redhat.com>
