Michal Hocko 1173ff09b9 watchdog: fix double lock in watchdog_nmi_enable_all ...

Commit ab992dc38f ("watchdog: Fix merge 'conflict'") has introduced an
obvious deadlock because of a typo.  watchdog_proc_mutex should be
unlocked on exit.

Thanks to Miroslav Benes who was staring at the code with me and noticed
this.
