kernel - Adjust count algorithm a little
* Remove an unnecessary pre-alignment. The division rounds down and will
take care of any mis-alignment with regards to calculating the correct
count value.
* Theoretically due to the fact that the slab is already aligned, and the
size is already aligned, and the division rounds down, the count
calculation will be correct. However we leave te safety code in and make
it a bit more robust just in case some programmer messes with the code
later on.
