Christophe JAILLET a811e4bc69 leds: trigger: ledtrig-cpu:: Fix 'output may be truncated' issue for 'cpu' 
[ Upstream commit ff50f53276131a3059e8307d11293af388ed2bcd ]

In order to teach the compiler that 'trig->name' will never be truncated,
we need to tell it that 'cpu' is not negative.

When building with W=1, this fixes the following warnings:

  drivers/leds/trigger/ledtrig-cpu.c: In function ‘ledtrig_cpu_init’:
  drivers/leds/trigger/ledtrig-cpu.c:155:56: error: ‘%d’ directive output may be truncated writing between 1 and 11 bytes into a region of size 5 [-Werror=format-truncation=]
    155 |                 snprintf(trig->name, MAX_NAME_LEN, "cpu%d", cpu);
        |                                                        ^~

        |                                                    ^~~~~~~
  drivers/leds/trigger/ledtrig-cpu.c:155:17: note: ‘snprintf’ output between 5 and 15 bytes into a destination of size 8
    155 |                 snprintf(trig->name, MAX_NAME_LEN, "cpu%d", cpu);
        |                 ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
