Subject: [PATCH 5.12 251/363] sh: Remove unused variable

From: Eric Dumazet <edumazet@...gle.com>

commit 0d3ae948741ac6d80e39ab27b45297367ee477de upstream.

Removes this annoying warning:

arch/sh/kernel/traps.c: In function ‘nmi_trap_handler’:
arch/sh/kernel/traps.c:183:15: warning: unused variable ‘cpu’ [-Wunused-variable]
  183 |  unsigned int cpu = smp_processor_id();

Fixes: fe3f1d5d7cd3 ("sh: Get rid of nmi_count()")
