Subject: [PATCH v3 1/3] MIPS: Remove noreturn attribute for nmi_exception_handler()

In the later patch, we will remove noreturn attribute for die(), in order
to make each patch can be built without errors and warnings, just remove
noreturn attribute for nmi_exception_handler() earlier because it calls
die(), otherwise there exists the following build error after the later
patch:

  arch/mips/kernel/traps.c:2001:1: error: 'noreturn' function does return [-Werror]
