iwlagn: add IRQ tracing
The legacy IRQs could be read from a trace by their IO accesses, but reading the ICT doesn't leave any trace (pun intended ;-) ) so in order to see what input they get we need to add specific tracepoints. While at it, fix whitespace in two related places. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
