x86/hpet: simplify hpet_get_channel()

There's no need for a lock here, elimination of which makes the
function a leaf one, thus allowing for better (and smaller) code.

Further, use the variable next_channel according to its name - so far
it represented the most recently used channel rather than the next one
to use.
