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().
