powerpc/32: Mark both tmp variables as unused
Since the value of `tmp` is never intended to be read, declare both `tmp`
variables as unused. Fix warning (treated as error in W=1):
arch/powerpc/kernel/signal_32.c: In function ‘sys_swapcontext’:
arch/powerpc/kernel/signal_32.c:1048:16: error: variable ‘tmp’ set but not used
arch/powerpc/kernel/signal_32.c: In function ‘sys_debug_setcontext’:
arch/powerpc/kernel/signal_32.c:1234:16: error: variable ‘tmp’ set but not used
