watchdog/core: Rename some softlockup_* functions 

The function names made sense up to the point where the watchdog
(re)configuration was unified to use softlockup_reconfigure_threads() for
all configuration purposes. But that includes scenarios which solely
configure the nmi watchdog.

Rename softlockup_reconfigure_threads() and softlockup_init_threads() so
the function names match the functionality.
