[Xenomai-core] [PATCH v2 1/5] x86_32: Fix NMI watchdog build for 2.6.27

[Jan Kiszka <jan.kiszka@domain.hid>]

Fix build breakage against 2.6.27-x86-32 due to changes of die_nmi. At
this chance, switch the internal function call wrapping to latest
unified mainline instead of using the legacy prototype.
