[PATCH 1/2] watchdog: Fix output

[Peter Zijlstra]

The pr_crap() functions generate idiotic output; use printk().

Broken output:

[ 3538.718135] NMI watchdog: BUG: soft lockup - CPU#2 stuck for 22s!  
[perf_fuzzer:2646]
[ 3383.233583] NMI watchdog: Watchdog detected hard LOCKUP on cpu 27

Fixed output:

[14180.328194] BUG: soft lockup - CPU#2 stuck for 23s!  [perf_fuzzer:13650]
[ 1064.914925] BUG: NMI Watchdog detected hard LOCKUP on cpu 11
