hpwdt: use nmi_panic() when kernel panics in NMI handler
Commit 1717f2096b54 ("panic, x86: Fix re-entrance problem due to panic
on NMI") introduced nmi_panic() which prevents concurrent and recursive
execution of panic(). It also saves registers for the crash dump on x86
by later commit 58c5661f2144 ("panic, x86: Allow CPUs to save registers
even if looping in NMI context").
hpwdt driver can call panic() from NMI handler, so replace it with
nmi_panic(). Also, do some cleanups.
