[PATCH smp v2 3/3] smp: Make symbol 'csd_bug_count' static

From: paulmck

From: Wei Yongjun <weiyongjun1@xxxxxxxxxx>

The sparse tool complains as follows:

kernel/smp.c:107:10: warning:
symbol 'csd_bug_count' was not declared. Should it be static?

Because variable is not used outside of smp.c, this commit marks it
static.
