MIPS: smp-cps: Fix potentially uninitialised value of core

Browse source

Turning on DEBUG in smp-cps.c, or compiling the kernel with
CONFIG_DYNAMIC_DEBUG enabled results the build error:

arch/mips/kernel/smp-cps.c: In function 'play_dead':
./include/linux/dynamic_debug.h:126:3: error: 'core' may be used
uninitialized in this function [-Werror=maybe-uninitialized]

Fix this by always initialising the variable.
