watchdog: move softlockup_panic back to early_param
Setting softlockup_panic from do_sysctl_args() causes it to take effect
later in boot. The lockup detector is enabled before SMP is brought
online, but do_sysctl_args runs afterwards. If a user wants to set
softlockup_panic on boot and have it trigger should a softlockup occur
during onlining of the non-boot processors, they could do this prior to
commit f117955a2255 ("kernel/watchdog.c: convert {soft/hard}lockup boot
parameters to sysctl aliases"). However, after this commit the value
of softlockup_panic is set too late to be of help for this type of
problem. Restore the prior behavior.
