printk.c: use unsigned ints instead of longs for logbuf index
Stop using unsigned _longs_ for printk buffer indexes. Log buffer is way
smaller than 2 gigabytes and unsigned ints will work too . Indeed, they do
work nicely on all 32-bit platforms where longs and ints are the same.
With this patch, we have following size savings on amd64:
text data bss dec hex filename
