printk_once(): use bool for boolean flag
Using the type bool (instead of int) for the __print_once flag in the
printk_once() macro matches the intent of the code better, and allows the
compiler to generate smaller code; eg a typical callsite with gcc 4.3.3 on
i386:
add/remove: 0/0 grow/shrink: 0/2 up/down: 0/-6 (-6)
function old new delta
static.__print_once 4 1 -3
get_cpu_vendor 146 143 -3
Saving 6 bytes of object size per callsite by slightly improving the
readability of the source seems like a win to me.
