[PATCH] watchdog: Fix build error when CONFIG_SOFTLOCKUP_DETECTOR is not set

[Laurent Dufour <ldufour@linux.ibm.com>]

Sachin reported the following build error when CONFIG_SOFTLOCKUP_DETECTOR
is not set:

kernel/watchdog.c:597:20: error: static declaration of 'lockup_detector_reconfigure' follows non-static declaration
 static inline void lockup_detector_reconfigure(void)
                    ^~~~~~~~~~~~~~~~~~~~~~~~~~~
In file included from kernel/watchdog.c:17:
./include/linux/nmi.h:125:6: note: previous declaration of 'lockup_detector_reconfigure' was here
 void lockup_detector_reconfigure(void);
      ^~~~~~~~~~~~~~~~~~~~~~~~~~~

The definition of lockup_detector_reconfigure should be exported even in
that case, and __lockup_detector_reconfigure should remain static.

Fixes: 24a1260705b7 ("watchdog: export lockup_detector_reconfigure")
