x86, mce: trivial clean up for mce-inject.c
Fix for:
WARNING: Use #include <linux/uaccess.h> instead of <asm/uaccess.h>
+#include <asm/uaccess.h>
WARNING: usage of NR_CPUS is often wrong - consider using cpu_possible(), num_possible_cpus(), for_each_possible_cpu(), etc
+ if (m.cpu >= NR_CPUS || !cpu_online(m.cpu))
ERROR: trailing whitespace
