bogomips are not consistent in SMP

[Costin Grigoras]

When allocating more than 1 cpu to a guest, the bogomips is ok only for the first one. For example:

# cat /proc/cpuinfo | grep -E "processor|MHz|bogomips"
processor       : 0
cpu MHz         : 2772.361
bogomips        : 5544.72
processor       : 1
cpu MHz         : 2772.361
bogomips        : 326.15
processor       : 2
cpu MHz         : 2772.361
bogomips        : 345.29
processor       : 3
cpu MHz         : 2772.361
bogomips        : 347.57
