Fix preemptible warning in aggsum_add()

In the new aggsum counters the CPU_SEQID macro should be surrounded by
kpreempt_disable)() and kpreempt_enable() calls to prevent a Linux
kernel BUG warning.  The addsum_add() function use the cpuid to
minimize lock contention when selecting a bucket, after selection
the bucket is protected by a mutex and it is safe to reschedule the
process to a different processor at any time.
