[PATCH 2/3] ipmi/watchdog: Use nmi_panic() when kernel panics in NMI handler

[Hidehiro Kawai]

commit 58c5661f2144 ("panic, x86: Allow CPUs to save registers even
if looping in NMI context") introduced nmi_panic() which prevents
concurrent/recursive execution of panic().  It also saves registers
for the crash dump on x86.

ipmi_watchdog driver can call panic() from NMI handler, so replace
it with nmi_panic().
