softlockup watchdog: style cleanups

kernel/softirq.c grew a few style uncleanlinesses in the past few
months, clean that up. No functional changes:

   text    data     bss     dec     hex filename
   1126      76       4    1206     4b6 softlockup.o.before
   1129      76       4    1209     4b9 softlockup.o.after

( the 3 bytes .text increase is due to the "<1>" appended to one of
  the printk messages. )
